These figures cover 323 flights between September 2025 and August 2026. The median arrival is 11 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 YX 4581 runs late
Carrier accounts for 43% of the 4,785 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 31%Late-arriving aircraft
- 24%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,057 of the 4,785 delay minutes reported here. The split is drawn from 4,785 delay minutes reported on YX 4581.
Cancellations run at 4.33%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
6.9% 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 close to two hours, which a normal layover absorbs.
The 1,231 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 323 flights under YX 4581 in the data flew TUL to LGA. 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. 323 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 YX 4581
For a booking, the cancellation rate is the figure to plan around on YX 4581: 4.33% of its 323 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
