These figures cover 268 flights between September 2025 and August 2026. The median arrival is 22 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.

Delay causes

Why B6 2821 runs late

Late-arriving aircraft accounts for 48% of the 2,144 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

Extreme weather

48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,144 reported delay minutes here, that single category outweighs weather by 24 to one. The split is drawn from 2,144 delay minutes reported on B6 2821.

Cancellations are rare at 0.37%, 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

5.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

At 2,039 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 268 flights under B6 2821 in the data flew MCO to LAS. 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. 268 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 B6 2821

For a booking, B6 2821 has one of the better records a US domestic flight can show: 89.5% on time and 0.37% cancelled. That is a base rate, not a promise about any single day.
