I just had to chuckle when I was reading through the new guidelines for baggage on the American Airlines site, found this:
Excess charges always apply to the following sports items:
Bicycle (if exceeding 70 lbs/32kgs or 62 in/157cm)
Scuba Tank (empty)
Wind surfing equipment
Hang gliding equipment
So, Kuki, something to beware of when traveling with AA, extra charges for the antlers!
