These figures cover 341 flights between September 2025 and August 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.

Delay causes

Why DL 808 runs late

Carrier accounts for 54% of the 2,653 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    54%
  • Late-arriving aircraft
    35%
  • National Airspace System
    9%
  • Extreme weather
    2%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,653 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 2,653 delay minutes reported on DL 808.

Cancellations sit at 1.17% against a national 1.89%, 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 2.4% 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 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.

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: 91.7% on time and 1.17% cancelled. That is a base rate, not a promise about any single day.
