How to Read a Flight Number and Airline Code
Your flight number is one of the fastest ways to identify the exact flight you need to track. It usually combines a short airline code with a number, such as AA78 or DL1234.
AA identifies the airline. 78 identifies the flight number used for that scheduled service.
Where to Find Your Flight Number
Airline Code vs. Flight Number
The letters at the beginning are the airline designator used with the flight number. The digits identify the flight service. When checking a flight, use the complete combination shown on your itinerary rather than searching by destination alone.
Why the Same Trip Can Show More Than One Flight Number
Some itineraries are sold through airline partnerships. In those cases, your confirmation may show a marketing flight number that differs from the operating airline’s flight number. If your lookup does not match what you expect, check the reservation for wording such as “operated by” and try the operating flight number as well.
Flight Number Tips
- Enter the airline code and number exactly as shown on your itinerary.
- Use the correct travel date, especially for overnight or international flights.
- If a flight is operated by another airline, check both the marketed and operating flight numbers if necessary.
- Recheck your flight near departure because gate and terminal information can change.

Is the airline code part of the flight number?

Can two airlines show different numbers for the same flight?
Yes. Airline partnerships can result in a marketed flight number and a different operating flight number for the same aircraft movement.
Does a flight number tell me my gate?
No. The flight number identifies the flight. Gate and terminal details are separate operational information and may be assigned or changed closer to departure.

Airline code plus number

Confirm more than the number
