Hi all,
My Dad's got a flight coming up KHI-DXB-LHR-ORD and return. Upto LHR is Emirates while the LHR-ORD is on AA

all in Business .... Since the DXB-LHR flight is an overnight flight (EK 007 on B777-300ER) he is thinking of upgrading to First using Skywards points so that he can get some sleep.
Is it worth it for this flight? Emirates can be so inconsistent in their product so its worth asking the experts... What can he expect in First?
Regards
Tayyab
