just flew F on YVR-DEL and my impressions mirror other posters.

pros:
-great service, very kind FAs, will try their best to make sure you are comfortable
-seat is very wide and unrestricted, even had bedding provided. got some great sleep
-food was delicious if you like Indian food
-TUMI amenity kits & PJs are quite nice
-direct flight with minimal hassle

cons:
-very tired interior, buttons and various seat pieces are very worn or barely working. even the USB port was just sputtering out power
-very limited IFE/barely functioning IFE. I can count the number of English movies that they offer and the moving map was broken
-limited food choice. seems like Indian food was the only option and it was between veg or non-veg? I get it's air india but perhaps offer a western option? especially for F....
-no menus so I had no idea what was available or what I even ate. would be nice for those not familiar with indian food vocabulary or just to see what there is on offer especially for drinks
-service was less proactive than other F airlines I've been on. usually, the FAs are like ninjas and will clear your plates immediately but this did not happen. not sure if one off or if this is the norm?

I did get an escort upon arrival in DEL. i was first to disembark but we disembarked via a bus gate so I ended up on the same bus as the other J pax which kind of defeats the purpose (I mean, I can get on the bus myself....). overall, AI F is alright if your final destination is India or if this is the fastest option to your destination or have no other choice. but if you had any choice, I'd probably choose any other airline unless there was a deep discount. I redeemed miles so I guess the hit was not as significant but it definitely pales in comparison to other F and even J on other airlines
