BA cannot park a/c up at LHR, there are no remote stands available for long term, they either need Farnbrough or Fairford.
I do believe they have choosen on Filton to park 2 up midweek however the major reductions due fuel are reducing frequency on routes rather than dropping altogether. The company is in good shape overall with such a good balance sheet. When compared with the likes of AA and UA which have lost about US3 Billion between them at least BA is in a strong position going forward.
The A380 and 787 orders have already been financed so are going ahead regardless of the credit crunch/fuel. Due to the price of fuel it means investment in more fuel efficient a/c becomes even more important.
