Delay & cancellation outlook for this flight
Early read, sample still buildingConditions at GMP and CJU are near their clear-air norm right now, so this reflects the route's recent baseline rather than a weather penalty. For this route and airline, under conditions like today's, over the last 90 days. This route's tracked sample is still thin — treat these as an early read, not a precise forecast.

How ZE261 actually runs
Pro Flight Search has tracked every published board update for ZE261 across the GMP and CJU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 2 completed legs so far: left noticeably late (~22 min) but landed right on schedule. Not enough to call it.
The verdict above is that record speaking, so it reflects how ZE261 operates rather than what the timetable promises. Numbers refresh as new flights operate.
