Don't get me started on ticketing skills at airports. Something like 20 years ago I had a RTW Star Alliance business class ticket. I was booked on a Thai flight Kuala Lumpur to Bangkok in economy because the particular flight only had economy. I turned up early for a flight that did have business. Nobody (and I mean NOBODY) at Thai understood the difference between "booked" and "paid" class they just looked at the booked class on the later flight and refused to understand that I had paid for business. BA are by no means the first people to do away with ticketing staff at airports.
