These figures cover 251 flights between September 2025 and August 2026. The median arrival is 9 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.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.4% 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 same number turns up on five other city pairs in the data, including LAS to PHX (182), CLT to BOS (76) and BOS to CLT (75), but none flew often enough under AA 1611 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHX to LAS only.
One caution: this is a thin sample. 251 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 1611
For a booking, AA 1611 has one of the better records a US domestic flight can show: 89.5% on time and 1.20% cancelled. That is a base rate, not a promise about any single day.
