Normally pay extra. Inform the airline before hand that you're bringing ski kit as you can be stung for extra if you just turn up with it. Normally between £15 and £25.
You'll pay extra with Wizzair, Easyjet and Balkan. I tried to blag it with Wizzair last year, got my boards to sofia no probs but got collared on the way back and had to pay a charge. However it was only he same cost as had I pre booked - but it was a real pain having to queue to check in, get knocked back and pointed to the queue to pay the charge and then queue again for check in
yes most chage. if u have book with a toroperator. they will arange it for u. it is just abit of a pain in the ass haveing to que agen to check ur skiis in. but thats life.
