These figures cover 274 flights between September 2025 and August 2026. The median arrival is 8 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2045 runs level with that at 90.5%. 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 2045
The latest arrival of the period was on 17 March 2026, 8 hours 20 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in March 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 March 2026 | 8 hours 20 minutes | Carrier |
| 16 March 2026 | 2 hours 3 minutes | National Airspace System |
| 18 March 2026 | 2 hours | Carrier |
| 26 October 2025 | 1 hour 50 minutes | Carrier |
| 21 October 2025 | 52 minutes | Late-arriving aircraft |
Delay causes
Why DL 2045 runs late
Carrier accounts for 60% of the 1,512 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Carrier
- 21%National Airspace System
- 20%Late-arriving aircraft
The largest share of delay minutes, 60%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 900 of the 1,512 delay minutes reported here. The split is drawn from 1,512 delay minutes reported on DL 2045.
Cancellations are rare at 0.36%, 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 1.5% 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.
At 1,888 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.
The same number turns up on one other city pair in the data, including DTW to ATL (26), but none flew often enough under DL 2045 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to TPA to SLC only.
One caution: this is a thin sample. 274 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 2045
For a booking, DL 2045 has one of the better records a US domestic flight can show: 90.5% on time and 0.36% cancelled. That is a base rate, not a promise about any single day.
