These figures cover 294 flights between September 2025 and August 2026. The median arrival is 10 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.

| 29 March 2026 | 4 hours 3 minutes | Carrier |
| 27 February 2026 | 3 hours 41 minutes | Carrier |
| 26 May 2026 | 2 hours 21 minutes | Carrier |

Delay causes
Why WN 312 runs late
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 2,121 reported delay minutes.
- 41%Late-arriving aircraft
- 38%Carrier
- 20%National Airspace System
- 0%Extreme weather
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,121 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 2,121 delay minutes reported on WN 312.
Cancellations sit at 1.36% against a national 1.89%, 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 4.1% 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.
The 674 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.
The same number turns up on 23 other city pairs in the data, including BNA to ECP (86), DAL to LBB (49) and SNA to OAK (36), but none flew often enough under WN 312 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ECP to DAL only.
One caution: this is a thin sample. 294 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 WN 312
For a booking, WN 312 has one of the better records a US domestic flight can show: 88.3% on time and 1.36% cancelled. That is a base rate, not a promise about any single day.
