I’m doing online check in with Jet2 (going to Majorca from Leeds Bradford ) They’ve got option to pay for Guaranteed cabin baggage. We’ve got a small cabin size suitcase among our hand luggage which might not fit under the seat if no space on the shelves. What people think, should I pay for this guaranteed place? The problem is that you are not allowed to pay for just one place, it will be for all who travels way to and from.
