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