Ryanair - combining allowances 4 hold baggage
Don't forget that you and Mrs SP have 15 kgs each hold baggage but if her case is 17kg and yours is 13kg you either have to repack or she pays XS on her 2 kilos! How that keeps the customers, or the people behind you at the chek in while you repack, happy I do not know! Calm down! Its only a stupid Ryanair moneymaking rule!
