How OS34 actually runs
Pro Flight Search has tracked every published board update for OS34 across the JFK and VIE boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left right on schedule but landed about 34 min early. Not enough to call it.
The verdict above is that record speaking, so it reflects how OS34 operates rather than what the timetable promises. Numbers refresh as new flights operate.
