Well it all depends on your priorities. Because shipping an extra bag on airlines is a standard 50 extra dollars. Mailing is almost always cheaper, but it is a little more wobbly. You could get there before your skis or they could get shipped somewhere weird, you just don't have your skis when your going to a resort, i dont really know. So it all depends on how much skrilla you got and how positive you are that your skis will get there. Personally i just pay 50 bucks so i know they will get there and i can have them as soon as i get to where i am going.
