BA is, indeed, a good choice for lifestyle. But not if you take an airbus command after 2 or 3 years (even if you think this will be possible, which I'm not convinced about in future years).
All that is going to happen next year is that a lot of senior people are going to take another look at short haul command and realise they are suddenly a lot more senior, relatively, than they would have been this year.
As was mentioned a few posts ago, those really junior pilots getting short haul commands this year could very well end up on blind lines with no weekends off for years. For some that won't matter, but if you have a family it very well might.
