Conditions at BUF and SJU 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 B6635 actually runs

Pro Flight Search has tracked every published board update for B6635 across the BUF and SJU boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 3 completed legs so far: left right on schedule but landed about 45 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how B6635 operates rather than what the timetable promises. Numbers refresh as new flights operate.
