When you see a segment line like this in a PNR, the airline code identifies Finnair:
2 AY 587 Y 15JUL 2*JFKLHR HK1 800A 2000P
The two-letter code AY at the start of the segment line is Finnair's IATA code — every flight segment operated by Finnair in a GDS PNR (Amadeus, Sabre, Galileo, or Worldspan) begins with this code, followed by the flight number.
Finnair is a finnish flag carrier, based in Finland, and is a member of oneworld. Its ICAO code, FIN, is used for air traffic control and flight planning, while its radio callsign is “FINNAIR”.
Once a AY segment is sold, the fare quote and ticketing entry differ by system. The starting point in each is:
Amadeus: FXP Sabre: WPNCB Galileo: FXP
Each of these prices the itinerary using the lowest applicable fare for the AY segment(s) in the PNR — the exact fare basis and rules still need to be checked against Finnair's current fare filing, since GDS pricing reflects what's filed, not a fixed rate.
As a oneworld member, Finnair participates in the alliance's interline agreements — member airlines typically coordinate on interline ticketing and reciprocal status benefits. In practice, this means a client's itinerary can often mix Finnair with other oneworld carriers on one ticket, which matters when pricing multi-carrier routings or handling irregular operations (delays, misconnections) that involve more than one airline.
Like most airlines, Finnair's fare classes follow the standard GDS booking-class letter system. See our complete booking class guide for what each letter (F, J, Y, and so on) typically means.
Finnair's IATA code is AY. This two-letter code appears at the start of every flight segment operated by Finnair in a GDS PNR.
Finnair's ICAO code is FIN. The ICAO code is a separate, usually three-letter identifier used mainly in air traffic control and flight planning, distinct from the IATA code travel agents see in a PNR.
