How DL1633 actually runs
Pro Flight Search has tracked every published board update for DL1633 across the DTW and IAH boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left noticeably late (~44 min) but landed noticeably late (~30 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how DL1633 operates rather than what the timetable promises. Numbers refresh as new flights operate.
