It's worth adding that Norwegian Europe's 3 rd biggest low cost carrier charge just a flat fee of £4 reservation for credit cards and no charge for on line checkin, I can't see Jet2 getting away with the on line checkin fee not being shown at the booking stage, you can't avoid it, so it should be included, it spoils what is otherwise a good product, shame they don't have confidence in their product to show true cost up front.
I have no problem with charges for bags and sports equipment and card fee's that reflect the cost of processing, but the rest is just misleading the true cost of a flight.
