byAir vs. Fly Delta

No. Keep Fly Delta for official actions such as booking changes, check-in, boarding passes, seats and upgrades, standby status, checked-bag tracking, SkyMiles, and rebooking. byAir complements it with independent flight tracking, multi-airline trip organization, imports, and traveler-focused alerts.

Yes. Add a Delta 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 Delta or other airlines.

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 Delta’s status remains the official one.

Use Fly Delta for official bag scans and real-time tracking tied to your Delta itinerary. byAir can help with baggage-claim details and airport guidance, but it does not replace the airline’s bag-tracking system.

Its public feature list describes SkyMiles balance and Medallion Status progress, 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.

That is where byAir is especially useful. It keeps flights from different carriers in one trip, including connections or separate tickets, so you can follow the journey without switching between airline apps.
