We don't, it's a rumour network where people make observations and opinions much like those you have made on this topic.
Indeed, and rumours and misinformation are also commonplace in the crew room and long sectors. Typically originating from old and bold ‘in the know’ types and then repeated. I flew on one contract for several years, and the perceived wisdom was that the client was paying for all staff, on the contract, to fly business class (as its own staff did according to its travel policies). The story was that our employer was then taking the difference in price to our economy flights to add to the contract revenue. 13 years later, I owned that contract and in no shape or form was there reference to contractor staff travel!
This was not the UK, but when I flew in Aberdeen the seasoned captains would have very similar pearls of wisdom they would recount, about the Oil companies, on the 032 radial (or 029?forget now which way round they were!) home with a nice headwind.
Anyway, I hope this is resolved swiftly and equitably.
