Best time to fly out of Mercedita (PSE)
Mercedita did not fly enough departures in this window to split the day into time bands. Not enough flights to say. A percentage needs at least 100 flights behind it before it is worth printing; anything thinner is noise wearing a decimal point. These are historical odds, not forecasts. The records say what happened on this schedule over three years; they know nothing about tomorrow’s thunderstorm.

What delays out of PSE were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 450 flights that departed PSE and ran 15 minutes late or more, the delay minutes break down with 77.1% put down to late-arriving aircraft and 12.5% to airline operations.
- Late-arriving aircraft 77.1%
- Airline operations 12.5%
- Air traffic & airport volume 10.1%
- Severe weather 0.2%
- Security 0.1%
Late-arriving aircraft is the knock-on category: the plane came in late, so it went out late again. It is why a 7am problem in Newark is still a problem in Denver at dinnertime, and why it is usually the biggest slice on the bar.
