No, it's as plank says: You have to go from Dubai, as long as there is the chance that with a 5' turnaround you could still remain within the FDR.
Once you realise that you will definitely exceed normal hours, at that time ask them where they want you to land. That'll make them jump and learn.
I repeat an earlier request:
Do not deal with them for going into any discretion or work on a day off by them removing a nasty turn on your roster, please.
It might suit you and definitely them, but you'll just shove down a nasty turn to one of your peers, no lesson learnt for the company and giving them the ticket to continue to abuse us.
