I would avoid any legacy AI 77W or 77L. The EY 77W first class is a good product. Will look a bit old but the amount of space is much bigger than J in A350. Also AI’s soft product in F is nice. You usually get taken to the gate (usually - which is nice). On AC it’s like 30% for for AI F over J - worth it. On UA it is like 50% more - not worth it. That all said, if I was on an old AI 77W - I would go with F because the seat is wide and true lie flat. Nonstop USA-India is just great any way you cut it and worth having small issues over other airlines (note I said small). Also I have noticed a difference between the AI crew based in BOM vs DEL. The BOM crew is better IMHO - like old school AI - were polite, speak well and have refined service. Also they treat older people very very well (If you are ever considering sending your parents in their premium cabins).
