The other is the high airport charges, particularly at Dublin.
Do you work for FR?
Seriously though, I think it's disingenuous to suggest that airport charges make that much of a difference in the grand scheme of things. If you're spending €500 on a holiday, the €10.43 charged per passenger at DUB is negligible.
Personally I'd much rather pay that fee to use a real airport rather than travel through a cattle shed like BVA.
