Hmmm, that reminds me of an incident I recall from a few years ago, when 1 enterprising CS operative within the BAEC decided to reserve a number of long-haul J seats on a flight she planned to take with her partner using staff travel concessions.
When it came to light she had held these seats to pretty much guarantee availability for an Op-up for the 2 of them, she was invited to leave the employ of BA rather quickly, despite 10+ years service. Tut tut tut
