byAir vs. United

Q: Does byAir replace the United app?

No. Keep the United app for official actions such as booking changes, check-in, boarding passes, seats, travel documents, checked bags, boarding progress, MileagePlus, agent support, and disruption recovery. byAir complements it with independent flight tracking, multi-airline trip organization, imports, and traveler-focused alerts.

Q: Can byAir track United Airlines flights?

Yes. Add a United flight manually, connect Gmail or Outlook, sync a calendar, forward the booking email, or scan a boarding pass or itinerary. The flight then appears alongside connections on United, partner airlines, or other carriers.

Q: Can byAir predict a delay before the United app?

On eligible flights, byAir Predict can show a clearly labeled predicted departure time and likely reason before the airline publishes a new official estimate. Coverage varies, not every delay can be predicted, and United’s status remains the official one.

Q: Does the United app show personal flight statistics across airlines?

Its public feature list describes MileagePlus account management and current-trip tools, but not a personal flight-history statistics dashboard. byAir combines completed flights from every carrier and calculates totals for flights, distance, time in the air, airlines, aircraft types, and airports visited.

Q: Which app should I use during a United connection?

Use the United app for official transfer time, gate information, boarding progress, terminal guidance, and your boarding pass. Use byAir to keep the United segments together with partner flights, separate tickets, and independent operational context.

Q: Which app should I use for checked bags and travel documents?

Use the United app for the Travel-Ready Center, official bag drop, bag scans, and disruption handling tied to your reservation. byAir does not replace those airline systems.

Use United to move through the airport. Use byAir to see the trip around it.

The United app is the official day-of-travel control center for a United itinerary. byAir adds an independent view of the entire journey.

Keep United for booking, check-in and boarding passes, seat or flight changes, the Travel-Ready Center, checked-bag tracking, boarding progress, connection guidance, terminal maps, MileagePlus, agent support, and self-service when a flight is disrupted.

Add byAir when the itinerary includes a partner or 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

United controls the United itinerary and airport journey. byAir adds an independent view across partners, separate tickets, and the rest of the trip.

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 United for official airline actions, then add byAir for independent flight intelligence across the entire trip.

What byAir users say

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.

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

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.

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