I've got a funny itinerary next week and just wanted confirmation that I can check my bag through on the following:
PNR 1 JFK-BOS (F) (5 hour layover for a meeting)
PNR 2 BOS-JFK-CDG-LUX (Air France La Premiere, BOS-JFK on DL, CDG-LUX on LG.)
I' planning to do some shopping in NYC and would like to drop a bag at JFK on my way to BOS to go along for the full ride. Possible?
