An interesting article, not just for Gatwick but for BA overall.
But I'm conscious of the fact that if you wait for something and it never turns up eventually you don't have any aircraft."
This seems to be a none-too-veiled reference to the 787.
BA has taken six of eight 777-300ERs it has on order
That's one of the problems for BA long haul. With only two 777s and a handful of A380s due in the next 3-4 years, the 787 still out of sight (because nearly a year after the first delivery, Boeing seems unable to manage more than a couple of deliveries per month, and BA is far the list), with all those new slots at Heathrow to fill, and the 747s and 767s getting ever older and needing more downtime, I just can't see where BA are going to get any significant long-haul capacity from for Gatwick.
Meanwhile BA is also turning its attention to the replacement of the ageing 737-400 fleet
The obvious replacement is the 10-15 year old A319 fleet currently at Heathrow, which regularly seem too small and could do with a significant tranche of A320s to replace them there.
