Am flying with WizzAir (yes, that's right!) on Saturday and they charge a fortune for baggage. We're going to attempt travelling with just 2 bags for 4 of us for a week (do-able) but I cocked up the booking process (finger slipped) and I appear to have booked and paid for 2 cases out, but 3 on the return journey.
Their website says no refunds if you check in with fewer than booked, but what if I notify them in advance, i.e. now? Reluctant to pay 77p a minute to wait in a queue on their helpline.
