FAQ

byAir vs. Southwest

Let Southwest run the booking. Let byAir watch everything around it.

The Southwest app is the official control center for a Southwest trip. byAir adds an independent view of the journey beyond the reservation.

Keep Southwest for booking changes, check-in, a Wallet-ready boarding pass, assigned-seat management, Priority Boarding, digital bag check and tracking, Rapid Rewards, and official day-of-travel alerts.

Add byAir when the itinerary includes another airline—or when you want a second operational view. byAir keeps every carrier in one timeline and turns completed flights into one cross-airline history with personal statistics. It also compares five flight-data providers, shows inbound-aircraft and airport-delay context, and uses byAir Predict to surface an early delay signal before the official estimate changes on eligible flights.

Use both apps for the jobs they do best

Southwest controls the Southwest reservation. byAir adds an independent view of the entire journey, including separate tickets and other airlines.

Add byAir to your travel stack

Your airline app manages the booking. byAir watches the journey.

The strongest setup is not a forced either-or. Keep Southwest for official airline actions, then add byAir for independent flight intelligence across the entire trip.

What byAir users say

Jose M Iturralde

Super easy and friendly app to track your flights, family, and friends. I use it when going to pick someone up at the airport too. Super useful, with lots of airport info.

Hardeep Singh

This is the best traveling and tracking app I have ever used. So easy and convenient. Everything is synchronized in one place.

Janet Osborne (JaLyn)

Excellent app for keeping track of my flights during an arctic freeze snowstorm. It kept me updated on delays and cancellations and helped keep my stress low.

Eli Lopez

Easy to add flights and track real-time delays before the airlines report them at the airport. So far it’s been great!

James Muri

I find that sometimes airlines don’t notify you about flight changes, but byAir is trustworthy in sending me flight information.

Drew Srk

This app transformed the way I travel. It gives me real-time flight updates, helps me navigate airports, and sends timely gate-change alerts.
