LGW is on the up now as far as BA are concerned... an extra 777 and a number of A319s for this years summer programme!
The number of 777s is a fraction of former years and even down on the consolidated fleets from 2005. There are up to 7 daily B777s out of LGW down from 9-10 in 2005.
Will BA invest in a B737-400 replacement against easyJet? People always say "yeah the A319s from LHR are coming" but they're still being heavily used at LHR and they won't be taking 25 A320s anytime soon to replace them. The decision has been pushed back to the end of the B734s useful life so they can't extend that any more even if they wanted to. Expansion at Madrid will cater for a lack of capacity at Heathrow, and I still believe when reality bites, they will *have* to put in a third runway at LHR. It's the least worst of a bad pile of options.
Tempting option : Consolidate Spanish routes with Iberia on larger capacity aircraft, free a small pile of slots up for the B777 leisure routes we are led to believe make money and move them to LHR. EuroGatwick closes as the B737s have reached the end of the road.
