Definitely over the center of Baghdad, which on Saturdays flight was so brightly lit it took me a while to figure out it was Baghdad (we were also flying at 25,000 feet at that time). Quatar and Bahrain to your right and if it is a night flight expect 40 mins of circling over the gulf south of Bandar Abas till DXB ATC lets you in.
DXB to CCU you will fly north, Hug the coast with Iran, Cross over into Pakistan somewhere near karachi follow the trail up a bit into India Over jaipur, South of Delhi, Kanpur and onto Kolkatta.
On a night flight not much one can see below.
On a foot note, you will have one of the older 330 on the DXB-CCU route. Most uncomfortable seats ever............that is in Y....
