I am NOT at Hainan but at another Chinese carrier but have 6 years experience flying in China. I would be VERY SKEPTICAL of this contract if you are NTR. They will pay you as a Captain once fully checked to the line but in reality you will not for at least 3 years the true PIC. You will fly as a Cruise Captain and your name will never be on the Dispatch release and Flight assignment as the actual PIC. China Southern, Hainan and Air China Cargo have been playing this racket for quite some time now. Ask the CS pilots after 2 years of flying as FO and Cruise captain on 787 and none of them have actually flown as the true PIC listed on the paperwork. Every job application I have ever filled out will state "Only list the actual PIC time as the time when you were assigned the PIC code on the Dispatch release." Essentially the flight time is FO flight time. Another big problem is Hainan will pay 60%for the first 3 months, after this you will be paid 70% until "Checked to the Line". This will take upwards of 1 year. Ask the A-320 guys who transitioned how long it took them before being fully checked to the line. Some are still flying as FOs after2 years. Another issue will be the commuting contract offers 11 days off in your base. These bases will be very slow to come forward and when they do you may not get 11 CONSECUTIVE days. For example if you choose Seattle as a base and you live in Phoenix then getting 2-3 days off in a block, several times per month at your base in Seattle will not help you as its too difficult to commute for such a short period of time. Hainan will state you get 11 days off per month but they may not be consecutive. Ask the Air China cargo pilots about this bait and switch tactic. In the end DO NOT trust a recruiter as they tell great LIES. Read your contract and pay special attention to all aspects and even then they will most likely ignore the plain language and do as they wish. If you want a 4 week on/4 week off contract my advice is stay n the narrow body fleets A-320 and B-737 and you will do fine. If you pursue these widebody aircraft you will be smoked upon continuously by Chinese pilots and ridiculed and harassed as an FO by the true PIC. It's not worth the pain to go there. All the best.
