In this article, http://www.timesonline.co.uk/tol/tra...cle4340518.ece, it was estimated that a flight from Heathrow to Edinburgh cost £60,000 to run.

So my calculation of income would be thus:

Airbus A320 = 156 seats

20 @ £40
20 @ £50
20 @ £60
20 @ £100
20 @ £120
20 @ £150
10 @ £230 (Business UK)

Thats 83% occupancy, with income of just £12700.

So does Domestic cost BA a huge sum of money?
