Hi.
Yes I have spoken to Delta, or rather Air France as it is from this side. They agree that the timings are crazy, as is the requirement to go to ATL at all if the flight is leaving from JFK. They are totaly sympathetic, but are unable to make the changes, as the booking was made by an agent i.e Orbitz. This still leaves me with the problem of contacting Orbitz. I agree they are ridiculously tight, especially with the 'bus' ride at JFK.
