These figures cover 365 flights between July 2025 and June 2026. The median arrival is 11 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.

Schedule

When DL 2808 flies

DL 2808 flies BOI to MSP without a single fixed slot. Its most common scheduled departure was 05:30, used on 121 of 365 flights, with 05:20 (86 flights) and 05:35 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 05:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2808 runs level with that at 90.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 2808 quarter by quarter

Quarter by quarter DL 2808 held fairly steady: 93.4% in Jul–Sep 2025, 84.6% in Oct–Dec 2025, 94.4% in Jan–Mar 2026 and 91.1% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights93.4%
Oct–Dec 202592 flights84.6%
Jan–Mar 202690 flights94.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2808 ranged from 86.3% on Sunday to 94.1% on Saturday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2808 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 2,728 reported delay minutes.

Carrier
42%
National Airspace System
36%
Late-arriving aircraft
21%
Extreme weather
2%

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,132 of the 2,728 delay minutes reported here. The split is drawn from 2,728 delay minutes reported on DL 2808.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.1% 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 1,142 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 365 flights under DL 2808 in the data flew BOI to MSP. 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. 365 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 2808

For a booking, DL 2808 has one of the better records a US domestic flight can show: 90.9% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
