| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 June 2026 | 8 hours 13 minutes | Carrier |
| 7 March 2026 | 7 hours 53 minutes | Extreme weather |

Delay causes
Why OO 6403 runs late
Carrier accounts for 62% of the 5,631 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 19%Late-arriving aircraft
- 11%Extreme weather
- 8%National Airspace System
- 0%Security
Extreme weather accounts for 11% 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 1.8 times the usual weather exposure. The split is drawn from 5,631 delay minutes reported on OO 6403.
Cancellations sit at 2.35% against a national 1.89%, which is ordinary. Diversions add another 0.39%.
Connections and routes
What a delay on this flight costs
10.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 551 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.
The same number turns up on one other city pair in the data, including DFW to SHV (18), but none flew often enough under OO 6403 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAF to DFW only.
One caution: this is a thin sample. 255 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 OO 6403
For a booking, read OO 6403 as 83.5% on time with 2.35% cancelled over 255 flights. Those are rates from the past twelve months, not a forecast for any particular day.
