How TP233 actually runs
Pro Flight Search has tracked every published board update for TP233 across the LIS and IAD boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left heavily delayed (~49 min) but landed noticeably late (~24 min). Not enough to call it.
The verdict above is that record speaking, so it reflects how TP233 operates rather than what the timetable promises. Numbers refresh as new flights operate.
