AirEuropa

If you fly with AirEuropa a lot or you're just looking for an app that lets you reserve a flight across Europe with Madrid (Spain) as the initial or final location, this app can help you search for and book flights in a few easy steps.

The app's interface is specially designed so you don't waste any time in making your reservation. It's organized in three easy steps: search for the outgoing flight, then the return flight if it applies, and then pay. All you have to do is select your original location, destination, and the date and time you want to travel. Once you've selected these elements, you just have to make the payment.

You can also use this app to check in and get your boarding pass without having to wait in long lines. Besides this, you can use the personal assistant to answer any questions you might have before, during, or after the flight.
