How 3U Appears in a GDS PNR

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.
