QR is upgrading around 10 F/Os per month. Expect four years if you join with experience. Doha is not as fun as Abu Dhabi or Dubai but QR is probably the much better choice in terms of overall working environment. Everyone I speak to on the line has a long term plan to stay, unlike five years ago when many pilots left. I also hear that several of those that left for Abu Dhabi are now returning to QR.
