This route lands a B, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That rests on 1,846 BWI to PVD flights, with a median arrival 6 minutes early.
Best time to fly BWI to PVD: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 94.7% of the time and Wednesday flights 87.6%, against 79.6% for the route overall.
The US average over the same twelve months is 77.3%, 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 1,846 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.

The most reliable ways to fly Baltimore to Providence
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 4 of the top 5 use a different airport at one end.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
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 32 points, against half a point between the best and worst carrier.

Scale runs 55% to 100%.
The 8pm–5am window is where this operation falls apart: 63.2% on time, against 94.7% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8pm–5am window is the busiest, with 381 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 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.
September is the best month on the calendar at 86.0% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. September was the busiest month here, with 172 flights.
Across the week, Wednesday is the strongest day at 87.6% on time and Sunday the weakest at 68.5%, a spread of 19 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 51% of the 18,000 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 31%Carrier
- 10%National Airspace System
- 8%Extreme weather
- 0%Security
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 18,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 18,352 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.7% on time here.
Cancellations sit at 2.28% against a national 1.89%, which is ordinary. Diversions add another 0.16%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.7% 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 327 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 86.9% on time across 1,850 flights, 7 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 7 points of difference.
The sample behind these figures is 1,846 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. September runs 86.0% on time and May 71.9%, a swing of 14 points. If the dates move at all, move them out of May before you think about anything else. 1,801 completed flights over 12 months sit behind that.
Common questions
BWI to PVD questions
How often is BWI to PVD delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 20.4% of the 1,846 flights in this analysis, against 22.7% nationally. Delayed flights are late by about 50 minutes on average.
How reliable is BWI to PVD compared with the rest of the country?
79.6% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on BWI to PVD?
The 5am–8am departure window is the strongest at 94.7% on time. The 8pm–5am window is the weakest at 63.2%, 32 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 May delays on BWI to PVD?
May is the weakest month at 71.9% on time, compared with 86.0% in September. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
