Always nice to be in J on EK 510 from DXB to DEL.

Though the flight time is only around 3 hrs , I usually get a good 2 hrs sleep and can reach DEL in good shape.

I usually have breakfast in the lounge (breakfast items starts appearing by around 3AM ) , board early and sleep.

Don't think you'll get much sleep at the DXB lounge as it's a fairly busy time when u land. The lounge will get quieter by 2 to 230 AM from memory.
