How long have you had it?
If the product isn't up to the task that it's advertised for then you have consumer rights. If you bought it recently, and it didn't survive one flight then that's pretty conclusive.
What I do? Well, I'm a Which? subscriber and I tend to mention that if they don't provide fair service then I'll be contacting Which? about my rights. Usually does the trick! ;-)
tbh I don't think the airline is in the wrong here... unless it can be shown they were extremely negligent with your clubs.
