How TK1421 actually runs

Pro Flight Search has tracked every published board update for TK1421 across the IST and TLL boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left right on schedule but landed about 13 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how TK1421 operates rather than what the timetable promises. Numbers refresh as new flights operate.
