This route lands a B, 4 points better than the national rate of 77.6%. About one flight in five arrive 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 2,693 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 2,693 flights between July 2025 and June 2026. The median arrival is 5 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.
Carrier by carrier
Which airline is most reliable on ATL to RIC
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

|---|---|---|---|---|---|
| Delta Air Lines | 2,624 | 81.6% | 57 min | 1.83% | B |
| Frontier Airlinesthin sample | 69 | 64.2% | 67 min | 2.90% | D |
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am268 flights90.7%
- 8am–11am414 flights89.4%
- 11am–2pm283 flights88.9%
- 2pm–5pm549 flights81.4%
- 5pm–8pm489 flights73.8%
- 8pm–5am690 flights74.3%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.7% of the time, against 73.8% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 690 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 24 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.
July is the worst month at 67.2% on time, 24 points below February, the best at 91.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 254 flights.
Across the week, Wednesday is the strongest day at 89.0% on time and Sunday the weakest at 72.8%. 16 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 54% of the 28,000 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.
- 54%Carrier
- 27%Late-arriving aircraft
- 16%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 15,000 of the 28,000 delay minutes reported here. The split is drawn from 28,322 reported delay minutes.
Cancellations sit at 1.86% against a national 1.81%, which is ordinary. Diversions add another 0.37%.
Connections and stage length
What a delay here actually costs
5.8% 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 are the about an hour kind, which a normal layover absorbs.
At 481 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 88.7% on time across 2,693 flights, 8 points above 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 8 points of difference.
The sample behind these figures is 2,693 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 91.4% on time and July 67.2%, a swing of 24 points. If the dates move at all, move them out of July before you think about anything else. 2,633 completed flights over 12 months sit behind that.
Common questions
ATL to RIC questions
How often is ATL to RIC delayed?
About one flight in five arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.8% of the 2,693 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
How reliable is ATL to RIC compared with the rest of the country?
81.2% of flights arrive on time here against a national 77.6%, a difference of 4 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on ATL to RIC?
The 5am–8am departure window is the strongest at 90.7% on time. The 5pm–8pm window is the weakest at 73.8%, 17 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 July delays on ATL to RIC?
July is the weakest month at 67.2% on time, compared with 91.4% in February. Across the year that is 24 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
