Stay with Skywards.
Emirates will be using one of there new A380s on this route as far as DXB, You will soon clock up the miles with them. If you fly j or F out of JFK on the late flight to DXB its Dinner at the Plaza on Emirates as well as the comp pick up and drop off from home. Emirates has low loads on this route thats why the comp dinner on the flight out, its a bit too much food for me.
