Hi Flyertalkers!

I would like to get some opinion on an itinerary I booked with my UA miles.

I'm currently booked: BKK(TG F)-NRT-FRA-JFK(LH F)

I'm considering changing to NRT-JFK (NH F) or NRT-FRA (NH C)

I won't be able to use the FCT in FRA as I can't access the schengen area, so that won't be a factor for me. Also, if I take NH, would 1:10 be enough for transit and lounge access? Let me know what you all think. Thanks for the input, much appreciated!
