Not sure many will have done this. I was in the BA hold pool but decided last year to stay orange after moving right to left. For me, as a 7000 hour pilot and 10 years experience, it was the thought of reverting to two stripes and many years waiting for an upgrade in the BA seniority process that influenced my decision. I am not sure I would choose to leave though once I had started. I have no real interest in long haul at this stage but I do not know what the next 10 years might hold. In some ways the time to command in BA makes it a more valuable prize.
