My understanding is that DL
will use the 764ERs on select European routes and sell the flights as all Y since the 764s do not have a Biz Elite cabin....the domestic first seats will be allocated to premium Frequent Flyers and those paying full or close-to-full coach fares. (similiar to AA
's approach on BOS
with its 752s) This arrangement will be in effect for the near-term future (for as long a domestic configured 764s are flying transatlantic) and will be eliminated once the 764s are equipped with a BizElite interior (its also possible that the 764s will return to domestic flying after the summer schedule and not be re-configured.....some of the new DL
transatlantic routes many only operate during the summer and/or DL
will cut capacity over the Atlantic for the winter timetable as most airlines traditionally do - too soon to tell exactly what the plan is.)
As for ATL
has always used domestic configuration aircraft on that route (as you point out, first the 752 and now the 764) and has never offered Biz Elite on the medium range ATL
service. Thus, DL
sells the domestic F seats as either F or J class (not sure which code they assign) and sitting in the front cabin requires a higher fare. Is it worth it (regardless of whether you pay for the upgrade in cash or miles)? Not really; while F class is always nicer that Y class, the F cabin on Delta's 764s only offers marginally more room that the Y class seats......its 6 across instead of 7 across and 38-39 inches of pitch compared to 31-33 inches of pitch. Inflight service is better in F (of course), but nothing special. DL
's 764s, in their present configuration, are designed to move a lot of people over short to medium haul routes, and its eveident when you are on board. A look at seatguru.com may help you make a decision.
upgraded the ATL
route to a 764 mainly due to high cargo demand, but pax numbers on the flight (from what I hear) are also rather good.
