If I was a betting man, Id have a wager that AL will make money out of the 350 orders by flogging them on, trade their current 330s for new ones as part of the deal. I think the company is too small to expand on it's long haul selection and the immigrant routes will be their main stay for the foreseeable future being Boston, JFK, ORD.
West coast, forget it.....cost a fortune to run unless a daily and the yields aren't there to justify a 365 operation.
This is all on the premise that the company's status quo re ownership. This may dramatically change in the next 12 months with the government making noises that heathrow slots are not as strategic anymore and the governments desire to imminently address the general pension problem that is a noose around its neck.
