More a warning than AIBU but got caught out by excess baggage costs lately. Only a suitcase each and each one was just over 4kg over. Expected to pay something but not £10 per kilo so an extra £90! Funny thing was on the return journey (from Greece) we had lost the extra weight...didn't realise 2 paperbacks and a shampoo made that much difference! Don't get me started on the extremely obese woman who sailed through without extra charges and spilled over into half my seat:( (Prepares to be flamed by all amply proportioned travellers:) )AIBU to feel just a teeny bit agrieved?
