Rosters on the 777 for FO's are an absolute nightmare compared to last year and the year before, specially if you are freighter and IRP qualified you will end up with 130 to 150 duty hours a month. Its a never ending tiredness - hotels are getting worse every now and then.
Example Flight ; DOH - DFW , blocktime in the range of 15,5 hours. You will spend approximately 22 hours at the hotel before going back. The latest experiment is a trial to remove the guaranteed OFF block of 4 which is randomly assigned in each month (without leave), instead you will be "able to bid" for days OFF . (We all know how well that works)
There is a clear trend in qatar airways over the last few years when it comes to flight crew T/C; down. Think twice before you jump onto this train.
