I thought TOM & TCX crews nightstop? They do from every other base......
God knows what GSM did, don't think they were overly bothered about following thr rules and regs!!
No they don't from any base. They do a return sector the same day, however they work to very strict limits when delays come into effect etc.
No UK charter airline; TOM / MON / TCX night-stop their crew in SSH unless of a delay or any other cause that would make them run out of operating hours... What made you think they night-stop down route?
