Yeah, do a search for "airlines" in the Touring forum... Flying with a bike is a quagmire... Lots of research and homework is necessary until you really understand the different airlines' policies... and the pitfalls
This. US carriers are a joke when it comes to traveling with bikes because they are charging up to $200 one way for a bike and/or oversized. When I flew with mine, I completely dissasembled it and called it "multi-sport" equipment and was not charged. On the return the charge was $30. Had it been in a bike box, the charge would have been $150 each way. For some, it may be better to buy a bike at the destination.
