With its revenue BA has to repay its debt, fund its pension black hole over the next ten years, it has to start renewing its fleet soon, it has to pay for employee cost rises, it would like to be able to pay a divi to shareholders (can't afford it yet), it has to pay for terminal five, and if the BAA has its way, will have to pay for the new runway at Stansted as well.
Apart for the runway at Stansted if BA fail in any of the above the company will sink and die.
Projections were made a couple of years ago as to how all this would be paid for, and then the price of oil triples.
Loco's have put thier prices up as well, they just don't call the rises surcharges so no news headlines.
