Transitory Profits
We can imagine that the huge increase in the profitability of British Airways is almost entirely due to the fall in the value of the pound. Parasite managers who, in fact, did nothing to achieve this will receive huge bonuses. Of course this is all transitory , but manager's bonuses, unjustified as they are at this time, are only one time. Pilots salaries once increased will continue at the increased level into the indefinite future.
