How WN1121 actually runs

Pro Flight Search has tracked every published board update for WN1121 across the CLE and DAL boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: left a little late (~15 min) but landed right on schedule. Not enough to call it.

The verdict above is that record speaking, so it reflects how WN1121 operates rather than what the timetable promises. Numbers refresh as new flights operate.
