American on TPA to PHL sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 1,674 flights, with a median arrival 6 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate American on TPA to PHL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 1,674 flights between July 2025 and June 2026. Beyond the headline rate, 12.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

American against every carrier on TPA to PHL

American flew 1,674 of the 2,614 flights on TPA to PHL, most of the route. Its 74.6% on time is about level with the route as a whole at 74.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Southwest at 76.6% to Frontier at 73.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When American runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 38 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am408 flights92.0%
  • 8am–11am287 flights83.3%
  • 11am–2pm271 flights75.4%
  • 2pm–5pm425 flights65.3%
  • 5pm–8pm283 flights53.8%
  • 8pm–5am

Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 53.8% on time, against 92.0% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 425 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.September best, December worst

December is the weak month at 65.5% on time, against 91.9% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 186 flights.

Across the week, Wednesday is the strongest day at 82.1% on time and Sunday the weakest at 67.5%. 15 points is a smaller lever than departure hour, but it is free.

Delay causes

Why American runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 59% of the 40,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    59%
  • Carrier
    20%
  • National Airspace System
    12%
  • Extreme weather
    9%
  • Security
    0%

59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 40,000 reported delay minutes here, that single category outweighs weather by 7 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 40,096 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 92.0% on time here.

Cancellations sit at 2.09% against a national 1.81%, which is ordinary. Diversions add another 0.12%.

Connections and stage length

What a delay here costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 920 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 74.5% on time across 1,675 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,674 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking American on TPA to PHL

Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 91.9% on time and December 65.5%, a swing of 26 points. If the dates move at all, move them out of December before you think about anything else. 1,637 completed flights over 12 months sit behind that.
