I understand it's a tough decision. Until end of last year, I would have suggested QR 777 fo hands down but now with the issues of being stuck in Barwa or Ein Khalid for years or a one bedroom in pearl with kids, 10-12 day freighter trip regularly (used to be once or twice a year) with deadheads of 15h+ in overbooked economy, poor chances of getting proper off days, it's not what it used to be.
For a single guy or if family can commute home it's still a brilliant gig in many aspects but for someone with a family with kids, impact on wife and kids will be big until they get more staff on line.
