DL Airline Code: Delta Air Lines IATA & ICAO
Delta Air Lines is stored in this dataset as IATA code DL and ICAO code DAL, based in United States. GDS segment lines print the IATA code before the flight number. Live routes, fares and baggage policies are not in this dataset.
Overview
DL is the IATA airline designator stored for Delta Air Lines. ICAO is DAL. Country of record: United States. On a cryptic GDS line the IATA code sits immediately before the flight number, for example DL 456. Agents should not confuse DL (two characters, sometimes a digit such as 6E) with DAL (three letters). This code page does not list routes, alliances, baggage rules, or fleet. Those facts are not in the dataset. Other United States carriers stored here: UA (United Airlines), AA (American Airlines), WN (Southwest Airlines), AS (Alaska Airlines), B6 (JetBlue), NK (Spirit Airlines). To decode a full itinerary that markets DL, paste the PNR into the parser.
How to use this page
- Find DL at the start of the flight line in the PNR.
- Paste the full itinerary into the PNR parser (or the GDS-specific parser if you know the host).
- Confirm the carrier name resolves to Delta Air Lines.
- Do not add baggage or meal claims that the PNR did not print.
Example
Example segment: 2 DL 456 H 26OCT 5 WLGAKL HK1 1945 2050 The parser should set marketing carrier DL (Delta Air Lines) and flight 456. Class H is a fare bucket, not proof of cabin without the booking-class tool.
