Also for winter schedule:

- JFK-FRA upgauges to 763ER from 752 (probably due to cancellation of CVG-FRA)
- JFK-BRU upgauges to 763ER from 752 (don't know why)
- JFK-PRG increased frequency to 5x weekly from 3x weekly (probably due to seasonal suspension of ATL-PRG and OK completely withdrawing TATL flights including JFK-PRG)
- JFK-SVO daily 763ER instead of usual winter reduced frequencies (probably due to seasonal suspension of ATL-SVO)
- JFK-LAX 6 out of 7 daily (weekday) flights to be on BE-equipped 752s
- JFK-BOS all mainline (M88, 738)

- ATL-MUC 764ER instead of 763ER
- ATL-MAD 764ER instead of 763ER
- JFK-DUB 763ER instead of 752

Since this IS Delta, I would probably count on more schedule and equipment changes as we head into the fall/winter...
