DL 808 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 341 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 808's record is 15 points better than the US average of 77.6%. That gap is worth roughly 153 fewer late arrivals for every thousand flights.

These figures cover 341 flights between July 2025 and June 2026. The median arrival is 14 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 808 flies

DL 808 flies TPA to DTW without a single fixed slot. Its most common scheduled departure was 06:00, used on 71 of 341 flights, with 08:30 (62 flights) and 05:40 (53 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 808 runs 4 points better at 92.9%. 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 808 quarter by quarter

Quarter by quarter DL 808 held fairly steady: 93.4% in Jul–Sep 2025, 93.4% in Oct–Dec 2025, 88.9% in Jan–Mar 2026 and 94.5% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 808 did best on Saturday at 100.0% on time and worst on Monday at 85.4%. Each day rests on about 49 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 808 runs late

One category carries most of the weight here. Carrier accounts for 60% of the 2,804 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
33%
National Airspace System
6%
Extreme weather
1%

The largest share of delay minutes, 60%, 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 1,683 of the 2,804 delay minutes reported here. The split is drawn from 2,804 delay minutes reported on DL 808.

Cancellations sit at 1.47% 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 3.0% 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 983 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 341 flights under DL 808 in the data flew TPA to DTW. 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. 341 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 808

For a booking, DL 808 has one of the better records a US domestic flight can show: 92.9% on time and 1.47% cancelled. That is a base rate, not a promise about any single day.
