"......they were the rules in place at the time of joining,...."
This applied to DEC's just as much!!! They were told that they'd fill up spaces unable to fill from inside due to the fast arriving 340-300's.
So stop bashing them and the guy's who had been promised accelrated cmd, they were lied to just as much, some however not to their detriment.
I just wonder what they tell the newcomers, not everyone reads Pprune.
