Conditions at SAT and BOS 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 DL816 actually runs

Pro Flight Search has tracked every published board update for DL816 across the SAT and BOS boards: schedule changes, gate pushes and actual clocks. Early read — pattern not clear yet. Only 1 completed leg so far: landed +75 min. Not enough to call it.

The verdict above is that record speaking, so it reflects how DL816 operates rather than what the timetable promises. Numbers refresh as new flights operate.
