These figures cover 359 flights between September 2025 and August 2026. The median arrival is 8 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.

The worst days
Worst days for AA 628
The latest arrival of the period was on 17 July 2026, 14 hours 22 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, January, October and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 July 2026 | 14 hours 22 minutes | Late-arriving aircraft |
| 27 January 2026 | 7 hours 47 minutes | Late-arriving aircraft |
| 26 October 2025 | 4 hours 43 minutes | Carrier |
| 20 November 2025 | 2 hours 59 minutes | National Airspace System |

Delay causes
Why AA 628 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 3,812 reported delay minutes.
- 34%Carrier
- 33%Late-arriving aircraft
- 24%National Airspace System
- 9%Extreme weather
No single cause dominates. carrier at 34%, late-arriving aircraft at 33% and national airspace system at 24% split the 3,812 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 3,812 delay minutes reported on AA 628.
Cancellations are rare at 0.56%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.5% 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.
Every one of the 359 flights under AA 628 in the data flew SNA to PHX. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 359 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 AA 628
For a booking, AA 628 has one of the better records a US domestic flight can show: 88.8% on time and 0.56% cancelled. That is a base rate, not a promise about any single day.
