using those secret airline codes like SQ, CX, QF and BR here on the so-called Professional Pilots Rumour Network.
Yes, some codes are better known than others. Yes, I could look up DL, to find Delta. I've flown as a Delta passenger many times, I just don't have their code memorized, and would be more happy to see the full name in the title of a thread. And, about secret airline codes, I worked for WB here in Canada (not Rwanda) decades back: Three 707's, then four DC-8-63's, and two L1011's. The Air Canada ramp guys would tell me that "WB" stood for "Water Buffalo", but that wasn't it!
That airline was forced to end its service due to changes in the economy, so I can empathize with the airline's challenges these days....
