I would not look for Delta to add a additional flight going into the low season even if the airport opens up the slots. They are planning a Saturday only flight from JFK. Best case at this point might be upsizing the ATL flight to a 757. In addition the Bomardiar Cseries aircraft that has some truly unique performance characteristics and may have opened up additional routes from smaller cities to places like STT are delayed due to the tariff issue. The aircraft would also be capable of Eastern US to EIS flights nonstop.
