EI Airline Code: Aer Lingus IATA & ICAO
Aer Lingus is stored in this dataset as IATA code EI and ICAO code EIN, based in Ireland. GDS segment lines print the IATA code before the flight number. Live routes, fares and baggage policies are not in this dataset.
Overview
EI is the IATA airline designator stored for Aer Lingus. ICAO is EIN. Country of record: Ireland. On a cryptic GDS line the IATA code sits immediately before the flight number, for example EI 456. Agents should not confuse EI (two characters, sometimes a digit such as 6E) with EIN (three letters). This code page does not list routes, alliances, baggage rules, or fleet. Those facts are not in the dataset. Other Ireland carriers stored here: FR (Ryanair). To decode a full itinerary that markets EI, paste the PNR into the parser.
How to use this page
- Find EI 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 Aer Lingus.
- Do not add baggage or meal claims that the PNR did not print.
Example
Example segment: 2 EI 456 H 26OCT 5 WLGAKL HK1 1945 2050 The parser should set marketing carrier EI (Aer Lingus) and flight 456. Class H is a fare bucket, not proof of cabin without the booking-class tool.
