Our flight database is world-class, but aviation records prior to 2006 don’t exist, and data from 2006 to 2011 is often incomplete.

Sometimes a flight isn’t in our system yet, and may take 1 to 24 hours to appear.

The most common reasons you can't find your flight are:

• The airline only recently added the flight, and our system is still syncing it.

• The flight is far in the future, and the airline hasn’t submitted it yet.

• Some airlines update the official flight database weekly instead of in real time.

• The airline quietly changed your flight number. Try searching by route instead.

If your search turns up empty, we automatically get a report.

Other reasons include:

• Airlines frequently adjusting schedules.

• Your flight is still months away.

• Some low-cost carriers only update once a week.

What if I still can't find my flight?

• Wait a few hours and try again.

• Tap “Tell us what’s wrong” at the bottom of the empty search screen to report it (we’ll review it, but you should not expect a reply)

• Try searching by route in case the flight number changed.

• For flights today, wait a few minutes and retry.

• For future flights, wait a few hours and retry.

• For past flights, add the flight manually
