So what was in the missing post? So far as I remember:
I’d found the bit about ski carriage charges in small print at the back OF THE BROCHURE (and quoted it, but there is no point in trying to repeat that now) [when the original complaint was about online booking].
I mentioned two old sayings (1) the labourer is worthy of his hire (meaning that the airline does have some extra costs to load and unload extra pieces of luggage - but the charge should be the same regardless of whether pre-booked or paid at the airport) (2) he who pays the piper calls the tune (meaning tour operators should not hide behind “airline rules” as an explanation: it is the charterers, i.e. the tour ops who should be dictating luggage rules ON CHARTER FLIGHTS to airlines, not the other way round: especially if the tour operator owns the airline!)
