And why do cargo pilots seem to get such a rough deal when it comes to rest rooms / facilities? If your counterparts with the airlines had to put up with some of the facilities you have to wouldn't there be an outcry?
Such a rough deal? As an adhoc cargo operator they may work to very relaxed limitations whereas they can do a month's work in a fortnight and take the rest of the month off.
The schedule may be by the day, not the hour or minute thus when they're ready to go to the airport they'll go and not before.
They will often be paid offshore, by the block hour or into overtime without that thing called taxation etc. etc. etc.
Yes, they'll work on aircraft perhaps without adequate toilet or catering facilities, they work hard but they play hard also and the financial rewards can be far higher, in the pocket, than those flight crew farting around with complaining passengers down the back!
