Has anyone had experience of this?

I took my road bike to majorca from leeds/bradford. They were really good with it – even saw the guy taking it out to the plane and he didn't kick it at all.

I seem to remember having to pay extra for the bike actually at the airport, as opposed to online but that was no big deal.

I paid £30 for my bike, and booked it at the time of booking my ticket..

Never had a drama.

Last year you could only pay at the airport, this year you can ring and book and pay when you book the ticket, you can't book the bike on online though.

I booked my bike online & just got back from the pyrenees with it.
You MUST have your own insurance for your bike as jet2 accept no responsibility for damage etc.
No problems though.

I've just got back from the alps,they do take online bike bookings now,just changed it i think,does give you piece of mind!
