These figures cover 255 flights between September 2025 and August 2026. The median arrival is 7 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.

A 09:55 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 2568 runs 5 points better at 88.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

The worst days
Worst days for DL 2568
The latest arrival of the period was on 2 January 2026, 6 hours 6 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 January 2026 | 6 hours 6 minutes | Carrier |
| 20 June 2026 | 3 hours 19 minutes | Late-arriving aircraft |
| 15 February 2026 | 3 hours 10 minutes | Carrier |
| 24 December 2025 | 2 hours 47 minutes | Late-arriving aircraft |
| 4 January 2026 | 2 hours 33 minutes | Late-arriving aircraft |
Delay causes
Why DL 2568 runs late
Carrier accounts for 48% of the 2,222 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 44%Late-arriving aircraft
- 9%National Airspace System
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,222 reported delay minutes here, that single category outweighs weather by 44 to one. The split is drawn from 2,222 delay minutes reported on DL 2568.
Cancellations are rare at 0.78%, 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 4.4% 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.
The 1,211 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 SAT to LAX (21), but none flew often enough under DL 2568 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to SAT 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 DL 2568
For a booking, DL 2568 has one of the better records a US domestic flight can show: 88.9% on time and 0.78% cancelled. That is a base rate, not a promise about any single day.
