There are bikes that will fit in suitcases which then become your trailer (bike friday) and some that fold well enough with the wheels off to fit in a suitcase (just measure the fold and buy one that fits both the bike and the airline requirements). Just make sure the suitcase is within the airline limit for size and weight with the bike inside; those extra fees are no fun.
Add Origami to the list of bikes that fit into suitcases that transform into trailers. Our Crane 8 does this perfectly with our Traveler case and trailer kit. And yes, the case comes in under 62 inches and the case with the bike and trailer packed inside is under 50 lbs.
