Airlines that charge for a second bag

[Roger Southwick]

Has anyone successfully used a company such as UPS for shipping dive gear to a vacation destination?  Have you found any helpful tips to share?

I'm heading to Cozumel in March, and the baggage fees (according to the ) for a 70lb roller bag with dive gear would be around $240 each way -- almost $1000 for 2 people, nearly doubling the cost of the airfare.
