Maybe two dozen for me (and mostly on the inbound back to SEA), which is why I have hesitated. If I could spend my life connecting through DEN and SFO, I wouldn't care. But with ORD, IAD, and LAX (all terrible terminal facilities), it just makes sense to have a place to park.

If I was in an airport 75-100, I'd be an RCC member.

And yeah, I'm really tempted to use miles. That way, if UA does go under, well least I got something out of it.
