remove the wheels, seatpost, and pedals. place the bike down on the bottom piece of foam. secure with the straps in the box. place the seatpost, pedals helmet running shoes wetsuit around bike. make sure you have placed supports where the skewers go. Place a piece of foam over the bike. place wheels on the foam and cover with the other piece of foam. put on lid. clasp buckles push down firmly but gently on the case and tighten the straps. retighten if top lid is loose. Put on a couple of luggage tags and off you go. Good luck.
American has a bike charge of 75 or 80 and an overweight baggage charge of 25. I always tell them its overweight right off the bat and have not been charged for the bike. I'd rather pay 25 than 75. don't forget to smile use the counter persons name, complement her hair etc. often that gets it on for free. or slip them a folded $10 for free passage.
