These figures cover 311 flights between July 2025 and June 2026. The median arrival is 15 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.
Schedule
When UA 2631 flies
UA 2631 flies EWR to SRQ without a single fixed slot. Its most common scheduled departure was 06:30, used on 55 of 311 flights, with 07:00 (43 flights) and 07:30 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 07:3041 flights13.2%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2631 runs 3 points better at 91.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why UA 2631 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 1,311 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.
- 46%Carrier
- 43%National Airspace System
- 7%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 600 of the 1,311 delay minutes reported here. The split is drawn from 1,311 delay minutes reported on UA 2631.
Cancellations sit at 0.96% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.3% land an hour or more behind schedule, against 8.1% 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.
The 1,034 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 same number turns up on three other city pairs in the data, including IAH to PHL (35), ORD to SAV (6) and BOS to ORD (6), but none flew often enough under UA 2631 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to SRQ only.
One caution: this is a thin sample. 311 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 UA 2631
For a booking, UA 2631 has one of the better records a US domestic flight can show: 91.9% on time and 0.96% cancelled. That is a base rate, not a promise about any single day.
