Have any of you road warriors seen AA permanently canceling any international flights yet? I need to book several trips to LHR thru spring and early summer on this route. Every time I look at availability, these flights are running way less than full. I keep hearing this route gets subsidized by Glaxo but I don't know if that's true, or if they will be able to keep subsidizing if they are. AA usually slaps a 777 on this route around May, and looks like that for sure ain't happening.

How long will AA wait before pulling the plug on an international flight? Oh, the perils of a small airport . . .

Thanks.
