byAir vs. KLM

Q: Does byAir replace the KLM app?

No. Keep KLM for booking changes, check-in, boarding passes, seats, extras, Flying Blue, and official updates. byAir adds independent tracking and one trip view across airlines.

Q: Can byAir track KLM and partner flights?

Yes. Import the itinerary from email or calendar, forward it, scan it, or add flights manually. byAir can keep KLM and partner-operated segments in one timeline.

Q: Can byAir predict a KLM delay?

On eligible flights, byAir Predict can show a clearly labeled predicted time and likely reason before the official estimate changes. Coverage varies, and KLM’s status remains official.

Q: Which app should I use for check-in and seats?

Use KLM for official check-in, boarding passes, seat changes, and airline extras. byAir tracks the trip but does not replace KLM’s reservation system.

Q: Does KLM show personal statistics across airlines?

Its public app listing focuses on KLM travel and Flying Blue, not a personal statistics dashboard spanning every airline. byAir combines completed flights from the carriers you add.

Q: Which app should I use for a multi-airline connection?

Use each operating airline for official documents and changes. Use byAir to place the flights together and monitor the connection with independent context.

Keep KLM for the booking and boarding pass. Add byAir for the complete trip.

The KLM app handles booking, itinerary management, check-in, boarding passes, seats, extras, Flying Blue, and official gate or schedule updates.

byAir adds one timeline across carriers, independent flight-data context, personal history and statistics across airlines, and early delay signals on eligible flights.

One official app. One independent trip view.

KLM controls its reservation, airline documents, and Flying Blue services. byAir connects that segment with partners, separate tickets, and the journey around it.

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.
