Delay causes
Why YX 4808 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 2,565 reported delay minutes.
- 38%Carrier
- 31%National Airspace System
- 18%Late-arriving aircraft
- 14%Extreme weather
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 2,565 delay minutes reported on YX 4808.
Cancellations sit at 1.39% against a national 1.89%, which is ordinary. Diversions add another 0.56%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.4% 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.
Every one of the 360 flights under YX 4808 in the data flew CMH to JFK. 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 YX 4808
For a booking, YX 4808 has one of the better records a US domestic flight can show: 88.1% on time and 1.39% cancelled. That is a base rate, not a promise about any single day.
