Talk Reaction, you don't work for a rival airline - you're in the military. There may be a crossover of skill but that's where is ends. Your attitude comes across as a little arrogant.
The BA comparison is only relevant when the forces want to retain people who might otherwise leave for the civi sector. In view of the lack of jobs out there and the redundancies in the forces there seems little reason to pay a retention incentive. It's also a flawed comparison when BA do in fact pay some of their admin staff very favourably and there are many parts of the Armed Forces where people work in far more dangerous and/or uncomfortable roles that require more commitment and at least equivalent levels of training/ability but they don't ever receive any extra pay (ie. nearly all combat arm units in the Army).
That said I'm not suggesting that everyone should be reduced to the same cr@p pay and share the poor moral but in the current climate those not in role will have their work cut out arguing why they deserve the extra pay and unfavourable comparisons might be drawn that question pay levels for those in role as well.
