Raingauge- I think you have answered your own question. 'If airlines are going to start to require endorsements'- real airlines don't require endorsements, only the pretend airlines do. Real airlines offer a remuneration package that staff will stay for hence turnover is negligible. The novelty of a shiny new jet will wear off after your fourth back of clock for the week, shortly thereafter you'll wonder why you cancelled the Flight International subscription. Cheers.
