What is an Ultra-Low Cost Carrier?

An ultra-low cost carrier, also known as ultra-low cost airline or abbreviated to ULCC, is an airline that operates with a low cost business model, meaning customers get tickets at a much lower cost.

Although both cheap, ULCC are not to be confused with a low cost carrier (LCC) as they operate a different business model, with unbundled fares and the result being cheaper prices of flights for customers. For example, on an ULCC, you will get a seat on a plane from one destination to another, but any extras such as baggage, selecting your seat or food are subject to an additional fee. Although not for everyone, ULCCs provide a cheap and convenient option for budget travellers who do not care for the extra ‘frills’.

These ultra-low cost carriers typically have fewer amenities than simple low cost carriers, and therefore have a greater range of add-ons for a fee.

The current ULCC tend to be American airlines, typically because domestic flights in the USA are shorter, have less frills and therefore are cheaper to operate. See the list below of the best ultra-low cost airlines for some examples of American ones, and also some others.

The best Ultra-Low Cost Carriers

Flying with an ULCC

Packing Light

To reap the most benefits of flying with an ultra-low cost carrier, and to ensure prices of your flights are kept down, you should try and pack as light as possible. Make sure to check how much baggage is included in the price of your ticket, as it varies airline to airline and some may include hand luggage whereas others will not. Find out the difference between personal items and hand luggage here.

With most ULCCs, you will have the option to book baggage onto your flight ticket. For some airlines, the ticket of a ULCC plus paying for baggage will still work out cheaper than other options, whereas some it may be cheaper to just book a flight which includes baggage in the first place. If you do, however, want to add baggage onto your flight, check out our how-to guide here.

Selecting a seat

Remember that with ultra-low cost carriers, it is cheap because the fares are unbundled so you only pay for what you want. You should check if you actually need that airline seat, and if the price is worth the view, extra room, or the ability to sit next to a loved one.

However, on many flights these days, whether a ULCC or not, you will have to pay to select a seat, so the price difference may not be much dissimilar. If you decide that you would like to book a seat for your flight, you can either do so at the point of purchasing your flight, or after through My Account. Read more about these different methods, including how to book the seats with Alternative Airlines here.

In-flight Entertainment

ULCCs tend to operate short-haul flights, so there is generally no hope for any in-flight entertainment such as movies or games on a personal TV screen. Instead, be prepared and save money by bringing your own personal device or tablet, or a magazine or book to keep you entertained.


Is flying with an ULCC worth it?

It totally depends on the traveller! If you are happy with simple air travel which gets you cheaply from one destination to another, then yes, ULCCs are totally worth it. However, if you are someone who doesn’t pack light, or who wants the ability to choose their seat, then LCC, hybrid airlines or full-service airlines may be the right option for you
