I've got an idea of things, but I'm not 100% sure. The last flight I've been on was a UA flight ORD-MSP operated by ShuttleAmerica. I asked the FA about their benefits, figuring SkyWest might be similar (he said it was). He said he had free flighs on Shuttle America (since that's his airline) and other UA flights (mainline, etc) cost $10 each way or something like that. Not too bad, and there are quite a few flights from ORD that SkyWest runs. I'm really interested in what they offer through DL, though, since SkyWest services them as well... they really cover South America and Europe, which I'd really like to see. Then again, maybe we should meet in HKG or something, eh Nick?
