As you know the effort is being made right now to go through the last few years worth of ID travel for all pilots to find guys that have started duty without adequate rest after commuting - several people have recently been in trouble over this - and a few more are about to get punished for past sins as they are found out....
while they are doing this, they are still PXing guys to a destination and getting them to operate straight away!
What is the difference of a guy flying in from BKK in the morning and operating in the afternoon compared to PXing to Bkk and operating back in the afternoon!?
