Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 36 points, against half a point between the best and worst carrier.
- 5am–8am109 flights82.2%
- 8am–11am192 flights80.3%
- 11am–2pm151 flights76.0%
- 2pm–5pm144 flights46.0%

Scale runs 40% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 82.2% of the time, against 46.0% for the afternoon window. That is 36 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 192 flights scheduled in it.
Across the year
JetBlue on CLE to BOS through the year
December is the weak month at 57.4% on time, against 90.5% in April. 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. September was the busiest month here, with 78 flights.
Across the week, Saturday is the strongest day at 78.4% on time and Sunday the weakest at 63.3%, a spread of 15 points.

The worst days
Worst days for JetBlue on CLE to BOS
The latest arrival of the period was on 16 March 2026, 14 hours 47 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 14 hours 47 minutes | Late-arriving aircraft |
| 27 December 2025 | 7 hours | Late-arriving aircraft |
| 22 May 2026 | 7 hours | Late-arriving aircraft |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 43% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 36%National Airspace System
- 18%Carrier
- 2%Extreme weather
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 23 to one. The split is drawn from 14,673 reported delay minutes.
36% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 5,341 minutes out of 15,000, against a national NAS share of 21%.
Cancellations run at 3.72%, against 1.89% nationally. That is about one flight in 25 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 costs
12.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 563 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.
The return leg is a different operation and performs like one: it runs 77.4% on time across 671 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.
One caution: this is a thin sample. 672 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 JetBlue on CLE to BOS
Put together: the delay figures matter less here than the 3.72% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 647 completed flights over 12 months sit behind that.
