A guide to picking your tri adventure chariot.

Which airline is right for you? Depends on one almighty question: Are you bringing your bike? Many airlines now let bikes fly as regular baggage—if you can get yours packed in a case weighing less than 50 pounds and measuring no more than 62 linear inches. (To determine linear inches, add the length, depth, and height of your bike box. E.g., A box measuring 29 x 19.5 x 12.5 is 62 linear inches.) If not—and it’s nearly impossible to fit a bike into a case that size—oversize or special bike fees may apply. Pick your partner for flight within the U.S. with these airline bike fees and tips below.
