Flying American this weekend to Tucson, want to bring a bike, just not sure which one or how. The web site says under 62 inches and not over 50lbs. Is that in a case/box? Can I just walk in to the counter with a bike and say I'm going to AZ? I was able to get a bike to France on Iceland Air, and I've heard some airlines allow you to walk in and bag the bike at the counter. Any Ideas? And what bike? I would like to ride some roads there, do a century or two, but I'm also interested in exploring the MTB trails there too. Any ideas?
