I have never transited in the U.S. from one airline to another when they were not in the same alliance and hence operated from the same terminal, QA and AA, for example. How do you handle your baggage in your situation? Jet Airways operates in terminal 8 while DL operates in 2-3 and 4. Does DL have representation.

Things have become so much better now. Travellers are much better informed now, thanks to sites such as FT. We were flying DEL-CDG-IAD in the 80's when AF cacnelled CDG-IAD flight and put us on IAD-JFK to connect to Eastern or some such airline in JFK and did not through check-in. We had to lug our bags from one terminal to another to check-in. We didn;t know any better. We got no compensation, nor did we know to ask for any. We arrived in Washington D.C. (DCA, instead of IAD) around midnight, instead of around 1:00 p.m.
