Yea, the AI flight will have AVOD, as will the EY flight.
I think EY would be a much nicer experience overall. I have flown AUH - JFK, though I haven't flown BOM - JFK on AI, so I can't compare.
50k EY miles will be useful when they have their next 50% discount redemption offer. IMO using the miles for a domestic ticket is a waste considering how cheap domestic fares are these days.
