Delta vs American: Airline Comparison Guide

Choosing between Delta and American Airlines can be tricky. Both are major US airlines with huge networks and millions of loyal passengers. You’ll see their names pop up whether you're flying short-haul or heading overseas.

This guide breaks down how they compare on the things that matter most - from seats and service to loyalty programs and travel perks. If you’re booking soon and want to know which airline works better for your trip, you're in the right place.

Let’s take a closer look 👇

✨Quick Answer: Is Delta or American Better?

• Delta is often preferred for domestic travel thanks to its reliable flight times and consistent onboard service. Travellers rate the customer experience highly, especially when flying economy or first class within the US.
• American Airlines stands out for its global reach and competitive loyalty programme. It’s a strong choice for international trips or frequent flyers who want access to more airline partners and upgrade options.

The better airline depends on your priorities. Delta makes everyday flying feel smoother. American may give you more value if you're chasing miles or flying long-haul.

At a Glance

Delta and American Airlines are two of the biggest names in US air travel. Both fly to hundreds of destinations worldwide and carry millions of passengers every year. If you’re booking a domestic trip or planning something long-haul, chances are one of these two airlines will be on your radar.

Airline size and reach 📏

• American Airlines operates the largest fleet in the world, covering more than 350 destinations across 60+ countries.
• Delta isn’t far behind, flying to over 275 cities on six continents with a particularly strong presence across the US and key international routes.

Alliances 🤝

• Delta is a member of SkyTeam, connecting you to partners like Air France, KLM and Korean Air.
• American belongs to the Oneworld alliance, which includes British Airways, Qatar Airways and Japan Airlines among others.

Major hubs 🛫

• Delta’s main hubs include Atlanta, Detroit, Salt Lake City and Minneapolis–St. Paul.
• American Airlines is centred around Dallas/Fort Worth, Charlotte, Chicago O’Hare and Miami.

Reputation 🗣️

• Delta is often seen as more reliable, with fewer delays and a smoother onboard experience.
• American’s strength lies in its global coverage and extensive route map, although it can receive mixed reviews on service consistency.

Basic Economy Comparison

Basic Economy fares are often the cheapest option on both airlines, though they come with important limitations. Delta and American each have their own rules, and it’s worth knowing what to expect before you book.

Carry-on rules 🎒

• Delta allows one carry-on bag and one personal item. That means space for a small suitcase in the overhead bin and a bag under the seat in front.
• American only guarantees a personal item with this fare. Unless you're flying transatlantic or qualify through status, a full-sized carry-on usually isn’t included.

Seat selection 💺

• Both airlines assign your seat at check-in. If you're hoping to sit with someone, it’s not guaranteed unless you pay to upgrade.
• Delta may offer the option to choose a seat for a fee, depending on availability.
• American rarely gives this choice on Basic Economy.

Boarding group 🚪

Travellers with Basic Economy tickets will board last. This reduces your chances of finding overhead bin space, especially on busy flights.

Other restrictions ⛔

You won’t earn many loyalty points. Tickets are non-changeable and non-refundable unless the airline cancels or significantly changes your flight.

Which feels more restrictive? 🤔

• American’s Basic Economy is tighter on what you can bring. Without a carry-on, you may have to check a bag and pay more.
• Delta is slightly more flexible and offers a bit more breathing room, especially for travellers flying light.

✨Our thoughts: If you’re going Basic Economy, Delta is the more traveller-friendly choice. That free carry-on adds real value, and the rules feel less punishing overall. American’s version may look cheaper upfront, but the extras can quickly add up.

Premium Cabin Comparison

Delta and American both offer premium cabin upgrades, though how those upgrades feel can vary depending on the route and aircraft. Here’s how the options stack up across both airlines.

Delta Comfort+ vs American Main Cabin Extra ✨

These are the extra-legroom seats in standard cabins, often found on domestic and short-haul flights.

• Delta Comfort+ gives you more than just legroom. You can expect priority boarding, dedicated overhead bin space and complimentary drinks on most flights. The experience feels a little more thought-through, especially on busy routes.
• American’s Main Cabin Extra also offers extra space, plus early boarding and access to overhead bins. You’ll need to check the aircraft, though, as the level of service and comfort can change from flight to flight.

Delta Premium Select vs American Premium Economy ✨

On long-haul routes, both airlines offer a step up from standard economy with wider seats, more recline and upgraded meals.

• Delta Premium Select cabins tend to feel more refined, with better lighting, reduced noise and slightly more privacy. Even the design and finishes help make it feel calmer.
• American’s Premium Economy gets the job done. There's good space and improved service compared to economy, but it doesn’t always feel consistent across the fleet.

Delta One vs American Flagship Business ✨

This is where both airlines go all out. Delta One and American Flagship Business are designed for long-haul luxury, with lie-flat seats, premium dining and airport lounge access included.

• Delta One feels polished and reliable, particularly on transatlantic routes. The cabin atmosphere is relaxed and the inflight service often stands out.
• American’s Flagship Business is strong on the right aircraft, especially newer wide-bodies. The seats are spacious and the onboard meals hold their own, though the experience can feel more hit or miss.

Domestic First Class ✨

If you're flying within the US, both airlines offer First Class with larger seats, priority services and complimentary food and drinks.

• Delta usually delivers smoother service and better flight punctuality. The cabin design often looks more modern too.
• American First Class can be solid for space, especially on newer planes, though travellers sometimes report mixed service levels depending on the crew.

✨Our thoughts: Delta wins on consistency across most premium cabins. Comfort+ and Premium Select feel more considered, and Delta One continues to impress. American has some strong offerings, especially in Flagship Business, though you might notice more variation depending on the aircraft and route.

Seat Comfort Comparison

Seat space on Delta and American is fairly matched, though small design details shape how comfortable each airline feels, especially on longer journeys.

Legroom and seat width📏

Standard economy on both airlines gives you around 30–31 inches of legroom. Seat width typically ranges from 17 to 18 inches depending on the aircraft. These measurements are standard across US airlines, so there’s little difference on paper.

Seat design and comfort 🛋️

• Delta tends to refresh its cabins more frequently, which shows in the quality of seat materials and layout. Many passengers say the cushions feel more supportive, especially on newer planes.
• American's seats can vary more depending on the route and aircraft type. On newer jets, the design is sleek and firm. On older aircraft, cushions may feel a bit worn and legroom can feel tighter, even when the numbers are the same.

Cabin layout and atmosphere 🛫

• Delta’s newer cabins include ambient lighting, modern seatback screens and tidier storage areas. These features can make the space feel more open, even when seats are the same size.
• American has updated many of its planes too, though some domestic aircraft still feature older interiors. Lighting and screen quality tend to vary more, which can change the feel of your flight.

Which airline feels more comfortable? 🤔

✨Our thoughts: On shorter flights, most travellers won’t notice a huge difference. If you’re flying for a few hours or more, Delta's newer interiors and softer seat finishes offer a slightly more relaxed experience. American isn’t far behind, but the mix of aircraft across its fleet means comfort can be harder to predict.

Frequent Flyer and Loyalty Programs

Delta’s SkyMiles and American’s AAdvantage are two of the most popular airline loyalty programs in the US. Each rewards you for flying and spending, though how they work and what you get from them can feel quite different.

Earning miles 💰

• With Delta SkyMiles, you’ll earn miles based on how much you spend on your ticket. It’s the same with American’s AAdvantage program. Higher fares mean more miles.
• Both programs also offer extra earning potential when you book through their partner airlines or hold a co-branded credit card.

Climbing the tiers ⬆️

• Delta uses a spend-based system called Medallion Qualification Dollars (MQDs). The more you spend, the closer you get to elite perks. There are no shortcuts, unless you hold a Delta Amex, which can help you reach status through spending.
• AAdvantage mixes spend and flight activity. You earn Loyalty Points through flights, credit card use and other eligible activities. It’s possible to climb tiers without flying constantly, which gives American’s program a more flexible feel.

Airline partners 🌐

• Both programs give access to global networks. Delta’s SkyTeam partnership includes airlines like KLM, Air France and Korean Air. AAdvantage works with the Oneworld alliance, which brings in British Airways, Qatar Airways, Japan Airlines and others.
• For travellers who often fly outside the US, American’s Oneworld connections offer strong coverage, especially across Europe, Asia and the Middle East.

Using your miles 💸

• Neither airline sticks to fixed pricing for award tickets. Delta dropped its award chart completely, so the miles you need can jump up during busy times. AAdvantage still gives you more of a guide - you’ll usually have a better sense of how many miles are needed for a flight, although peak dates can still mean higher prices.
• Both let you use miles for seat upgrades, partner flights and extras like bags or lounge passes, depending on your tier.

Long-term value 🏆

• SkyMiles is popular with domestic flyers and those loyal to Delta’s service. If you book regularly and don’t mind variable pricing, the program can work well, especially if you use a Delta Amex to boost your balance.
• AAdvantage appeals to travellers looking for more flexibility and global reach. The Loyalty Points system means you don’t have to fly constantly to level up, and international redemptions often give better value per mile.

✨Our thoughts: If you fly mostly within the US and already have a Delta Amex, SkyMiles will feel more rewarding. For international trips or anyone looking to earn status without always being in the air, AAdvantage makes it easier to move up the ladder. Both programs have value - it really comes down to where you’re going and how you like to earn.

Travel Credit Card Options

If you’re loyal to either Delta or American, a travel credit card can unlock more than just miles. These airline-branded cards come with benefits that make frequent flying feel smoother - from priority perks to money-saving extras.

Delta SkyMiles® American Express 🔴

• Delta’s cards, issued by American Express, reward loyalty with a bundle of travel perks. Many cardholders get a free first checked bag, early boarding and the chance to earn SkyMiles on everyday purchases.
• Some of the higher-tier cards also include lounge access and can help you reach Medallion Status faster by offering MQD boosts. For travellers focused on Delta’s loyalty program, these cards are often worth it, especially if you fly regularly.

American Airlines AAdvantage® Cards 🔵

• American’s credit cards come from Citi and Barclays. Perks vary depending on the card, but most include priority boarding, a free checked bag and the ability to earn AAdvantage miles on daily spending.
• Some cards unlock Admirals Club access, which is ideal for frequent flyers who value airport comfort. There are also bonuses that make it easier to qualify for elite status, which is useful if you’re aiming for Loyalty Points.

Which one makes more sense? 🤔

• If Delta is your go-to, the Amex range adds value by making travel feel more rewarding. From early boarding to lounge access, it helps turn loyalty into perks.
• Flying American more often? The AAdvantage cards are a strong match, especially if you're working towards elite status or want a smoother airport experience.

✨Our thoughts: Both cards deliver useful perks, but your airline of choice should lead the decision. Delta’s Amex cards feel more focused on status boosts and comfort upgrades. American’s cards offer flexibility and can help fast-track loyalty for frequent flyers. Either way, if you travel often, having one in your wallet can make each trip feel a little easier.

Routes, Destinations and On-Time Performance

Delta and American Airlines both cover a huge chunk of the map, though their strengths lie in different areas. If you're flying within the US, you'll find both offer extensive domestic coverage. The difference comes down to which cities they serve best, and how reliable their flights tend to be.

Where they fly 🌎

• Delta connects passengers to more than 275 destinations across six continents. It’s especially strong on transatlantic routes, with solid coverage in Europe and a growing presence in Asia. If you're flying from the East Coast or South, Delta’s network often offers more direct options.
• American Airlines serves over 350 destinations in 60+ countries. Its network includes more Latin American and Caribbean cities than any other US airline. Travellers heading to Mexico, Central America or the Caribbean often find American has the better route.

Domestic vs international 🏠

• American’s hub cities, like Dallas/Fort Worth, Charlotte and Miami, give it a strong presence across the Southern US and gateway access to Latin America. It’s a go-to for travellers flying between the States and destinations further south.
• Delta has deep domestic roots, with key hubs in Atlanta, Detroit and Salt Lake City. That makes it ideal for coast-to-coast flights or connections across the Midwest and Southeast. Its global reach is solid, but the real strength is in US domestic routes.

On-time performance ⏱️

• Delta is known for running on schedule. In recent years, it’s topped industry lists for punctuality and operational reliability. Fewer delays, fewer cancellations and smoother day-of-travel experiences make it a favourite for time-conscious flyers.
• American doesn’t score as highly for on-time arrivals, with more mixed reviews on reliability. It’s still a safe and dependable airline, but travellers with tight connections might notice the difference.

✨Our thoughts: Pick Delta for strong domestic routes and a better shot at being on time. Choose American if you're heading to the Caribbean or Latin America, or flying from one of its major hubs like Dallas or Miami. Both have serious global reach - the right choice depends on where you’re flying from and what matters most to you.

Baggage, WiFi and Lounges

When comparing Delta and American Airlines, it helps to look beyond the ticket price. The extras, like baggage allowance, onboard WiFi and lounge access, can shape your whole journey.

Baggage rules 🧳

Both airlines include a personal item and carry-on bag with most fares. That changes if you're flying Basic Economy.

• Delta lets Basic Economy passengers bring a full-size carry-on and personal item. American’s Basic Economy also includes a carry-on, although this wasn’t always the case - it was added more recently.
• Checked bag fees are usually the same. Expect to pay around $35 for the first checked bag unless your ticket type, status or credit card offers a waiver.

WiFi on board 📡

• Delta is rolling out free WiFi for SkyMiles members on many domestic flights. Coverage is expanding, and the connection tends to be stable for messaging and light browsing.
• American offers paid WiFi on most of its fleet. It’s available gate-to-gate, and you can usually purchase access in advance or onboard.

Both airlines have their strong points. Delta wins on cost-free access, while American offers reliable coverage across nearly all aircraft.

Lounge access 🛋️

Travellers flying in premium cabins, or those holding elite status or eligible credit cards, can access lounges with either airline.

• Delta’s Sky Clubs are found across major airports. They offer WiFi, drinks, snacks and space to relax before boarding. A Sky Club membership or Delta One ticket usually provides entry.
• American runs Admirals Clubs across the US and beyond. These lounges offer similar features, though entry requirements may vary depending on your card, fare or status.
• For long-haul international travel in Flagship Business, American also operates Flagship Lounges in select locations. These are more exclusive, with elevated food and drink options.

✨Our thoughts: Delta makes domestic flying a little easier with free messaging and expanding WiFi perks. Lounge access is solid with both airlines, though American's Flagship Lounges add something extra for international premium travellers.

Fees and Extra Charges

Hidden costs can catch you out if you’re not careful, especially on lower fares. Here’s how Delta and American Airlines compare when it comes to extra charges.

Baggage fees 💰

Both airlines charge around $35 for your first checked bag on most economy tickets. If you’ve booked Basic Economy, the inclusions start to differ.

• Delta includes a carry-on and a personal item, which gives you a bit more flexibility upfront.
• American’s Basic Economy only allows a personal item. If you’re bringing a full-sized carry-on, you’ll likely need to check it and pay for it at the airport, unless you hold elite status or pay with an eligible credit card.

Change and cancellation fees 🚫

• Most main cabin and above fares now allow changes without extra fees. That applies to both airlines across domestic and many international routes.
• Basic Economy is a different story. Delta’s version is more forgiving if you grab a ‘no change fee’ promo, while American typically sticks to strict no-change rules on these low fares.

Other charges to know🫰

Extras like in-flight meals, WiFi and entertainment can come with a price tag, depending on your cabin and route.

• American charges for WiFi on most flights. Delta is rolling out free WiFi for SkyMiles members across its domestic network, which helps if you’re flying often.
• Add-ons like priority boarding, seat upgrades or lounge access are available with both airlines, although usually tied to your ticket type or loyalty status.

✨Our thoughts: Delta comes out slightly ahead for flexibility, especially if you’re flying Basic Economy with a carry-on. American’s more limited baggage allowance and stricter ticket rules can catch some travellers off guard.

Safety, Support and Overall Experience

When choosing an airline, trust goes beyond just safe take-off and landing. It’s also about how you’re looked after when things don’t go to plan. Here’s how Delta and American Airlines compare.

Safety and trust 🔐

• Delta has built a strong reputation for reliability. Flight delays are less common, and passengers regularly highlight smooth boarding, clean cabins and aircraft that feel well looked after.
• American, while meeting the same safety standards, sees more mixed feedback. Maintenance and punctuality can vary more between hubs, which can affect overall confidence among regular flyers.

Customer support 📞

• Delta tends to respond quickly when things go wrong. Many travellers say it's easier to speak to someone helpful and get issues sorted without too much back and forth.
• American has made changes to improve service, especially with online tools and app features. Even so, some travellers still struggle to get fast, effective help during disruptions.

Overall experience 🧑‍✈️

• Flying with Delta usually feels more consistent, whether you're in economy or up front. From check-in to landing, the airline is known for polite crew members and smoother in-air service.
• American can deliver a great experience too, especially in Flagship cabins and newer aircraft. However, reports of inconsistent service and patchy communication mean it doesn’t always hit the same mark.

✨Our thoughts: Both airlines are safe and capable, though Delta generally wins for smoother operations and stronger customer support. If reliability is a priority, Delta is more likely to keep your journey on track.
