1. length of preceding duty is min rest. Can reduce to 10hrs in hotel down route. Normal is just under 24hours although MNL, DPS and a couple of others have been 12-13 recently. You will get 8days off per month in Doha. When freighter in exceptional circumstances you get days off down route.
2. FO entitled to business when deadheading and use of bunk if in economy and on company business. Not much deadheading to begin with. IRP will deadhead more as will freighter pilots.....rumour is freighter will be guaranteed business soon.
3. Don’t know
4. Process is starting around 4 years, but who knows. Has slowed up again recently.
5. Only you can decide that. I would say Barwa, but I know some guys choose to live there.
