These figures cover 365 flights between September 2025 and August 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 June 2026 | 2 hours 58 minutes | Carrier |
| 3 February 2026 | 2 hours 4 minutes | Extreme weather |
| 17 July 2026 | 1 hour 36 minutes | Carrier |

Delay causes
Why DL 484 runs late
Carrier accounts for 65% of the 982 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Carrier
- 17%National Airspace System
- 9%Late-arriving aircraft
- 8%Extreme weather
The largest share of delay minutes, 65%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 643 of the 982 delay minutes reported here. The split is drawn from 982 delay minutes reported on DL 484.
Cancellations are rare at 0.55%, 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 1.4% 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.
At 2,218 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 365 flights under DL 484 in the data flew MCO to LAX. 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. 365 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 DL 484
For a booking, DL 484 has one of the better records a US domestic flight can show: 94.5% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
