B6 126 lands a B−, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 297 flights, with a median arrival 6 minutes early.

Set against the rest of the country, B6 126's record is 5 points better than the US average of 77.6%. That gap is worth roughly 52 fewer late arrivals for every thousand flights.

These figures cover 297 flights between July 2025 and June 2026. The median arrival is 6 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 B6 126 flies

B6 126 flies TPA to JFK without a single fixed slot. Its most common scheduled departure was 06:45, used on 50 of 297 flights, with 07:00 (48 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 06:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 126 runs 7 points worse at 82.8%. 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

B6 126 quarter by quarter

B6 126 did not run the same all year. Its best quarter was Jul–Sep 2025 at 98.8% on time and its weakest Jan–Mar 2026 at 71.1%, a swing of 28 points on roughly 74 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, B6 126 did best on Thursday at 89.5% on time and worst on Monday at 73.8%. Each day rests on about 42 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 126 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 2,911 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
57%

30%

57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 2,911 reported delay minutes here, that single category outweighs weather by 57 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 2,911 delay minutes reported on B6 126.

Cancellations run at 3.70%, against 1.81% nationally. That is roughly one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

6.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The 1,005 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 297 flights under B6 126 in the data flew TPA to JFK. 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. 297 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 B6 126

For a booking, the cancellation rate is the figure to plan around on B6 126: 3.70% of its 297 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
