Has anyone ever flown Virgin Atlantic from JFK to London through/via Delta? I'm looking at fares and flights for next May (around the 24-25). I found a very reasonable fare for JFK to Gatwick, which would work for me because I usually end my trips in Lewes and it's easier for me to fly out of LGW than LHR. I have a large number of points with Virgin and am earning more with my credit cards. I'm hoping to be able to go business/first class which is called Delta One. So I'm wondering 1) Can I transfer my Virgin miles to Delta? Would I be booking on Virgin's site, then? 2) Does anyone have experience with Delta One, and if so, how did you like it?
Sorry if some of these are silly questions. Thank you!
