When you see a segment line like this in a PNR, the airline code identifies Sichuan Airlines:
2 3U 587 Y 15JUL 2*JFKLHR HK1 800A 2000P
The two-letter code 3U at the start of the segment line is Sichuan Airlines's IATA code — every flight segment operated by Sichuan Airlines in a GDS PNR (Amadeus, Sabre, Galileo, or Worldspan) begins with this code, followed by the flight number.
Sichuan Airlines is a asian flag carrier, based in China. Its ICAO code, CSC, is used for air traffic control and flight planning, while its radio callsign is “SICHUAN”.
Once a 3U 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 3U segment(s) in the PNR — the exact fare basis and rules still need to be checked against Sichuan Airlines's current fare filing, since GDS pricing reflects what's filed, not a fixed rate.
Like most airlines, Sichuan Airlines'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.
