Emirates!
Usually prefer the economy class in one of the big three middle eastern airlines : Etihad, Qatar or Emirates during my Germany-India round trips.I will write a comparison on my experiences on the three.
Emirates:
Pros:
Good legspace on flights from India to Dubai and from Dubai to Germany as well.Excellent in flight entertainment system ICE.Good food!The A380 deserve a special mentionas I felt the seat screens were bigger and the seats were even more comfortable.
