Every carrier on SJU to DFW, 975 flights

These figures cover 704 flights between September 2025 and August 2026. The median arrival is 13 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

American against every carrier on SJU to DFW

American flew 704 of the 975 flights on SJU to DFW, most of the route. Its 82.7% on time is 2 points better than the route as a whole, which runs 80.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from American at 82.7% to Frontier at 71.1%. Two 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.

Darker means more delays. Figures are on-time percentages.July best, January worst

January is the weak month at 62.5% on time, against 93.4% in July. 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. April was the busiest month here, with 86 flights.

Across the week, Friday is the strongest day at 89.2% on time and Saturday the weakest at 73.3%, a spread of 16 points.

Delay causes

Why American runs late on this route

Carrier accounts for 49% of the 9,473 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    49%
  • Late-arriving aircraft
    37%
  • National Airspace System
    12%
  • Extreme weather
    2%

37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,473 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 9,473 reported delay minutes.

The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,650 of the 9,473 delay minutes reported here.

Cancellations sit at 1.70% against a national 1.89%, which is ordinary. Diversions add another 0.85%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 2,165 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg is a different operation and performs like one: it runs 69.4% on time across 703 flights, 13 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 13 points of difference.

One caution: this is a thin sample. 704 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking American on SJU to DFW

Put together: treat all of this as provisional. 704 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 82.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 686 completed flights over 12 months sit behind that.
