You're digging too deep here.

Those are only partial schedules, CO will not be loading the complete May 06 schedules for at least a few months time. I can guarantee IAH-NRT, EWR-MEX, and IAH-GRU are not going anywhere.

Heck, the Winter 05/06 schedule isn't completely loaded yet. Let's wait until January or February before we start losing our collective mind over schedule reductions, shall we?
