Historical statistics for July 2025 to June 2026, not live status. For today’s AA 628, check with American Airlines.

AA 628 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 360 flights, with a median arrival 7 minutes early.

Set against the rest of the country, AA 628's record is 11 points better than the US average of 77.6%. That gap is worth roughly 113 fewer late arrivals for every thousand flights.

These figures cover 360 flights between July 2025 and June 2026. The median arrival is 7 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 AA 628 flies

AA 628 is scheduled to leave Santa Ana (SNA) at 06:45 local time and reach Phoenix (PHX) at 08:19. That slot held for 307 of the 360 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 628 runs level with that at 88.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

AA 628 next to SNA to PHX

Across its whole network American Airlines managed 74.4%, which this flight beats by 15 points.

Across the year

AA 628 quarter by quarter

AA 628 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Oct–Dec 2025 at 83.5%, a swing of 11 points on roughly 90 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202588 flights93.2%
Oct–Dec 202591 flights83.5%
Jan–Mar 202690 flights84.3%
Apr–Jun 202691 flights94.5%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AA 628 did best on Friday at 100.0% on time and worst on Sunday at 68.1%. Each day rests on about 51 flights, so a gap of 32 points is worth noticing but could still narrow in another year.

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 2,934 reported delay minutes.

Carrier
36%
National Airspace System
31%
Late-arriving aircraft
21%
Extreme weather
12%

Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 2,934 delay minutes reported on AA 628.

Cancellations are rare at 0.28%, below the national 1.81% 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 4.2% 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.

Every one of the 360 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. 360 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: 88.9% on time and 0.28% cancelled. That is a base rate, not a promise about any single day.
