These figures cover 266 flights between September 2025 and August 2026. The median arrival is 5 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.

By weekday, DL 1593 ranged from 80.0% on Friday to 91.9% on Tuesday. With about 38 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 265 completed flights by arrival against schedule.
8 of 31 late departures made up the time and arrived on time, 26% of them. In the other direction, 14 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SLC.
The worst days
Worst days for DL 1593
The latest arrival of the period was on 20 September 2025, 3 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 September 2025 | 3 hours 52 minutes | Carrier |
| 5 May 2026 | 2 hours 36 minutes | Carrier |
| 8 August 2026 | 2 hours 36 minutes | Late-arriving aircraft |
| 19 March 2026 | 2 hours 21 minutes | Late-arriving aircraft |
| 5 July 2026 | 2 hours 17 minutes | Carrier |
Delay causes
Why DL 1593 runs late
Carrier accounts for 46% of the 1,997 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 35%Late-arriving aircraft
- 19%National Airspace System
- 0%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,997 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 1,997 delay minutes reported on DL 1593.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 3.8% 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 1,404 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 four other city pairs in the data, including MSP to MSY (24), MSY to MSP (24) and MSO to SLC (23), but none flew often enough under DL 1593 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BNA to SLC only.
One caution: this is a thin sample. 266 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 1593
For a booking, DL 1593 has one of the better records a US domestic flight can show: 86.0% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
