Before 1AM: Shows all non-departed flights left that day (6/21). Everything seems fine.
After 1AM: Shows all flights for that day (6/21), including flights that have already departed (which, doesn't make any sense). Also, if I change the search time until 8PM, to only show the actual remaining flights of the day, it gives me a different list than the before 1AM search. In this example, the plane changed from showing as a 763 to a 757 and the departure time was skewed (DL 1406 LAX -> DTW), when the 763 is the correct plane. Also, the seat map is no longer available.
Anyway, this isn't uncommon behavior, and whacky things seems to happen at every 1AM EDT when the red-eye flights still haven't left yet! Thanks
The GDS we use is based in central time and 1pm Eastern is midnight central time, so the GDS is changing over then.
The error message for the seat map search comes directly from Delta. Since 1am EST represents 1 hour before departure, it could be under airport control at that time. Or, DLs host system just can't handle the time date difference at that point, either way it is nothing we have control over.
