We'll see... I don't understand your argument however; you say it is impossible to grow in 2012 due to slots but in 2013 there will be capacity expansion??? What about that slot problem.... where will they put those new aircraft?
In my view the london airports will squeeze out as much capacity as they can for the olympics. How will all those people get to london otherwise???
Doesn't really change anything though, growth plans are very easily changed into fleet freeze or even downsizing if the economy suffers bad enough.
Personally I don't see any reason for capacity increase in the UK after the olympics if this economic crisis continues, certainly not for the prices BA is asking.
