I posted to the Air Travel forum as well but thought I would ask Asia experts here. Any thoughts on best flights to India from among KLM (from Amsterdam), Air France (from Paris) or Jet Airways (from Amsterdam or London)? We would be in first/business class connecting from a Delta flight from Minneapolis. Likely to/from New Delhi but might be to/from Mumbai. Any particular reasons for quality of airline service or most efficient connections or any other factors?

I have used Delta/KLM via Amsterdam to Delhi several times and have been very satisfied with the service.

You may currently avoid Jet Airways. It has been a very good carrier but of late is facing financial difficulties. Every day they are cancelling / rescheduling flights.
I am very positive that they will put the difficulties behind quickly.
Happy travels!
