My plans in detail
I'm planning on flying the UAL Dreamliner from EWR to FRA. Check into Airport hotel, shower, nap and train to Heidelberg for the afternoon/evening. Fly LF A320 to BER the next day. Last time I was in Berlin was in the 70s. Lots to see/experience.
Fly AF A321 to Paris, CDG. Lived in Paris in the 80s. Been back many times. Paris is my heart's home. Love France. Love/hate les francais.
Fly RAM A321 to Casa/transfer to RAM Dreamliner to JFK.
I hope to do this trip in May. If Covid-19 prevents it then, September.
Thanks for all your tips.
