what about IAH-LHR on Continental? It can't be that hard to get to IAH from OKC, I'd imagine. There are only 2 flights compared to 3 on AA, but if there's anybody on CO that sees this (I'm pretty sure there are a couple that drop by every now and then) you never know if there's a lighter load elsewhere. Plus, there are two BA flights, rather than one (probably wouldn't help much, but you never know... if anything, that's one more alternative airline for everyone else)
