I want to take my bike to California from ohio on vacation. What's better, the airlines or ship it fedex,etc.?

Question

It's a bicycle

Answer 1

The airlines will charge it as over sized or excess baggage which is really pricey (like $300), but call your airline to find out.  Fed Ex or UPS ground is probably more reasonable.  The cheapest would be to buy a cheap bike at Target for $100 and make do for your vacation, then either sell the bike or give it away.

Answer 2

Bike as in bicycle or bike as in motorcycle?

Either way you'll probably have to ship it, but there are various ways to do it.
