Back in the late 1980s I took my bike around the Highlands and Island with BA (well, a BA painted aircraft!)
In GLA, it was handlebars turned to be in line with the frame, tyres deflated etc.
In Stornaway and Benbecula, the ground staff watched me starting the prep and asked: what are you doing? I explained.
"So how are we meant to push the bike to the aircraft?" they, not unreasonably, asked. I explained it was the rules.
"Those people in Glasgow have nothing else to do with their time than think up some crazy rules!" came the reply!
