Historical statistics for January 2026, not live status or a forecast for this year’s January. For today’s conditions at PIT, see live FAA status.

PIT in January carries a cancellation problem, not just a delay problem: 6.0% of scheduled flights never operate, against 4.7% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,099 flights, of which Republic Airways flew 872 at 84.2% on time.

PIT across all twelve months

These figures cover 3,099 departures from Pittsburgh International in January 2026. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

January next to PIT's other months

Against PIT's own year, January ran 2 points worse than the twelve-month rate of 81.4%, which makes it number eight of twelve months, best first. Cancellations are where January stands out: 6.03% of scheduled departures were called off, 3.1 times the airport's rate across the year. Either side of it, December ran 73.2% on time and February 83.6%, so this month sits in line with its neighbours.

Departure window

The best time of day to leave PIT in January

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against 5 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am894 flights81.2%
  • 8am–11am656 flights83.5%
  • 11am–2pm506 flights78.4%
  • 2pm–5pm386 flights76.0%
  • 5pm–8pm596 flights74.9%
  • 8pm–5am61 flights71.2%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 83.5% of the time, against 71.2% for the overnight window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 894 flights scheduled in it.

Across the week, Wednesday is the strongest day at 86.8% on time and Sunday the weakest at 65.7%. 21 points is a smaller lever than departure hour, but it is free.

Delay causes

What held PIT up in January

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 49,000 reported delay minutes.

  • Carrier
    39%
  • Late-arriving aircraft
    24%
  • National Airspace System
    23%
  • Extreme weather
    14%
  • Security
    0%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the comparison with the other months below is the more useful view of the risk. The national share is 10%, so this operation carries roughly 1.4 times the usual weather exposure. The split is drawn from 49,296 reported delay minutes.

Cancellations run at 6.03%, against 4.71% nationally. That is roughly one flight in fifteen cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

7.5% of arrivals land an hour or more late, close to the national 7.6%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

What to do with this

Flying from PIT in January

For a January trip through PIT: expect 79.2% on time and 6.03% cancelled, going by January 2026. The 8am–11am window was the strongest part of the day.
