At Alternative Airlines, you can search and book connecting flights across 600+ global airlines, even when those airlines don’t traditionally work together.
Thanks to our partnership with Amadeus and their virtual interlining technology, you can unlock travel routes not usually available elsewhere.
Connecting flights with multiple airlines allow you to travel between destinations using flights from different airlines on one booking.
Unlike traditional codeshare or interline agreements, virtual interlining pairs flights from independent airlines into one easy travel plan.
Virtual interlining uses a smart algorithm to scan millions of flight schedules across independent airlines. It then builds simple, time-saving and cost-effective connections into a single, bookable travel plan.
So, you can fly from A to B via C, even if those airlines don’t usually coordinate with each other.
For example, you could fly from Lincoln to Austin via Denver, with the first leg on United and the second on Frontier.
Our technology finds that combination for you, often offering a more direct and affordable route.

Sometimes. If the airlines you're flying with don’t have a baggage transfer agreement, you may need to collect your luggage and check it in again at the connecting airport. We’ll always let you know during the booking process if this applies to your flight.
If one of your flights is delayed, it could affect your connection. That’s why we recommend selecting itineraries with longer layover times. This gives you more security in case of unexpected delays.
