How BY49 actually runs

Pro Flight Search has tracked every published board update for BY49 across the CUN and LGW boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 2 completed legs so far: left a little late (~15 min) but landed about 27 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how BY49 operates rather than what the timetable promises. Numbers refresh as new flights operate.
