I guess a bargain depending on which Airlines they fly. If it is US Air or United, it's $200 a pop per way, so you'll end up with a $400 bill. And United sometimes make a point of asking you if you have a bike inside the suitcase or if the case itself is an oversized item other than the 62" linear inch. We had friends flying United to Arizona and they are nothing but vultures once they got wind you've got a bike!
