These figures cover 274 flights between July 2025 and June 2026. Beyond the headline rate, 13.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When NK 894 flies

NK 894 flies FLL to STT without a single fixed slot. Its most common scheduled departure was 12:55, used on 61 of 274 flights, with 07:15 (43 flights) and 13:00 (29 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 12:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and NK 894 runs 10 points worse at 69.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

NK 894 quarter by quarter

NK 894 did not run the same all year. Its best quarter was Jul–Sep 2025 at 85.5% on time and its weakest Jan–Mar 2026 at 39.8%, a swing of 46 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, NK 894 did best on Tuesday at 81.1% on time and worst on Saturday at 58.5%. Each day rests on about 39 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why NK 894 runs late

One category carries most of the weight here. Carrier accounts for 42% of the 4,893 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.

Carrier
42%
National Airspace System
42%
Late-arriving aircraft
16%
Extreme weather
0%

42% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,038 minutes out of 4,893, against a national NAS share of 21%. The split is drawn from 4,893 delay minutes reported on NK 894.

Cancellations sit at 1.09% against a national 1.81%, which is ordinary. Diversions add another 0.36%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 1,107 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 274 flights under NK 894 in the data flew FLL to STT. 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. 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 NK 894

For a booking, NK 894 is a flight to put a long connection behind. 13.0% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
