Pavel. Most of the concern on this thread is from UK based skiers. The issues they face with carriers tend to be connected with weight and money. The carrier's view is that skiers take more weight away with them, and that can make them money.
So with that in mind:
1.Stuffing your ski bag with clobber is now a no-no with B.A. who now have inserted a clause in the booking conditions. Most of the budget airlines have a weight limit on ski kit, even if you reserve space and pay. Expect to be questioned on the contents at check-in.
2.Offloading your ski bag to a little old lady in the check in line might work...if you give her the cash to check your kit in, and ask her to lie to the check in staff when they ask "Did you pack your bags yourself?" Second thoughts...not too wise a strategy in this age of terrorism threats. Many airlines in the UK have punitive charges for failing to reserve space.Tour Operators in the UK often double the charges for booking skis onto a flight at check in.
3.Many UK airports
and airlines have a nonsense rule about no ski boots as hand luggage. Various excuses have been used, my favourite this week is "It's the steel toecaps"
Today, an aquaintance told me that his daughter had her ski boots taken off her at security on her way to skiing in Europe last week. She was lucky to get them back on her return. She felt obliged to purchase more in resort. As she was late, she was not in the mood to put up a fight to keep her boots.
We are driving to skiing FNO, or taking the train, as flying from the UK to well, anywhere is just stressful.
