Was last week in Barcelona (Girona) and flew with Ryanair. We had one case to check in which was 15.7 kilos in weight. As the limit is 15 we were willing to remove some contents to hand luggage but the girl at the desk in Shannon said not to bother but to be careful on the way home. On the way home, we proceeded to pack the hand luggage (2 carry bags) with everything we could possibly get into it on the return to such an extent that the case was much lighter but when it was weighed at the airport it revealed 16.2 kilos. We queried this with the check in attendant but he didn't want to know and demanded €15. We refused and packed even more into the hand luggage and by the time we had finished, the case was nearly feather light and still weighed in at 14.5. We believe that there was no more than two thirds of the contents of the case coming home compared to going out and it still weighed heavier. There is something amiss.
