OO 4822 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about 2.1 hours on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 9 minutes early.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 12.7% 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 OO 4822 flies

OO 4822 flies GRI to DFW without a single fixed slot. Its most common scheduled departure was 06:11, used on 61 of 365 flights, with 05:09 (60 flights) and 05:19 (58 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 06:11 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 4822 runs 12 points worse at 77.2%. 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

OO 4822 quarter by quarter

OO 4822 did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.0% on time and its weakest Apr–Jun 2026 at 66.7%, a swing of 22 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.

Jul–Sep 202592 flights89.0%
Oct–Dec 202592 flights76.7%
Jan–Mar 202690 flights75.9%

By weekday, OO 4822 did best on Friday at 86.3% on time and worst on Monday at 70.6%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4822 runs late

One category carries most of the weight here. Carrier accounts for 73% of the 10,000 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.

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 10,204 delay minutes reported on OO 4822.

Cancellations sit at 2.47% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

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. 12.7% 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 562 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 OO 4822 in the data flew GRI to DFW. 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 OO 4822

For a booking, OO 4822 is a flight to put a long connection behind. 12.7% 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.
