These figures cover 364 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 OO 4229 flies

OO 4229 flies HIB to MSP without a single fixed slot. Its most common scheduled departure was 11:00, used on 83 of 364 flights, with 10:50 (65 flights) and 10:59 (46 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 11:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4229 runs 7 points better at 85.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 4229 quarter by quarter

OO 4229 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.2% on time and its weakest Oct–Dec 2025 at 79.5%, a swing of 13 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, OO 4229 did best on Saturday at 94.1% on time and worst on Sunday at 81.6%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4229 runs late

One category carries most of the weight here. Carrier accounts for 59% of the 4,666 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
59%
Extreme weather
34%
National Airspace System
6%
Security
1%

Extreme weather accounts for 34% 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 5.4 times the usual weather exposure. The split is drawn from 4,666 delay minutes reported on OO 4229.

Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.8% 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 an hour and a half, which a normal layover absorbs.

OO 4229 is not only a HIB to MSP flight. It also flew MSP to HIB (364 flights, 88.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 364 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.
