This route lands a B−, 6 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That rests on 723 ANC to BET flights, with a median arrival 6 minutes early.
Best time to fly ANC to BET: a 11am–2pm departure, ideally on a Wednesday. Flights in that window arrived on time 88.0% of the time and Wednesday flights 89.3%, against 83.4% for the route overall.
Set against the rest of the country, this route's record is 6 points better than the US average of 77.3%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 723 flights between September 2025 and August 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.

Departure window
The best time of day to leave
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 723 flights.

- 8am–11am160 flights82.2%
- 11am–2pm188 flights88.0%
- 2pm–5pm—
- 5pm–8pm361 flights81.3%
- 8pm–5am—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 88.0% on time, ahead of 5pm–8pm at 81.3%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 361 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 26 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
January is the weak month at 64.2% on time, against 90.3% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 89.3% on time and Monday the weakest at 77.5%, a spread of 12 points.
Delay causes
Why this route gets delayed
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,929 reported delay minutes.
- 42%Carrier
- 36%Late-arriving aircraft
- 13%Extreme weather
- 9%National Airspace System
- 0%Security
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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.2 times the usual weather exposure. The split is drawn from 5,929 reported delay minutes.
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,929 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 3.04%, against 1.89% nationally. That is roughly one flight in 30 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 stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.0% 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.
At 399 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 70.9% on time across 723 flights, 13 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 13 points of difference.
One caution: this is a thin sample. 723 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 this route
Put together: the delay figures matter less here than the 3.04% cancellation rate. A late arrival costs you roughly 50 minutes; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 698 completed flights over 12 months sit behind that.
Common questions
ANC to BET questions
How often is ANC to BET delayed?
About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 16.6% of the 723 flights in this analysis, against 22.7% nationally. Delayed flights are late by roughly 50 minutes on average.
How reliable is ANC to BET compared with the rest of the country?
83.4% of flights arrive on time here against a national 77.3%, a difference of 6 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on ANC to BET?
The 11am–2pm departure window is the strongest at 88.0% on time. The 5pm–8pm window is the weakest at 81.3%, 7 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are January delays on ANC to BET?
January is the weakest month at 64.2% on time, compared with 90.3% in May. Across the year that is 26 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
