JetBlue on BOS to CLE lands a B−, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 671 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on BOS to CLE from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 38 points, against half a point between the best and worst carrier.
- 5am–8am130 flights91.1%
- 8am–11am133 flights91.4%
- 11am–2pm119 flights77.4%
- 2pm–5pm46 flights84.8%
- 5pm–8pm177 flights64.1%
- 8pm–5am66 flights53.1%
Scale runs 45% to 95%.
The 8pm–5am window is where this operation falls apart: 53.1% on time, against 91.4% for the 8am–11am 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 5pm–8pm window is the busiest, with 177 flights scheduled in it.
Across the year
JetBlue on BOS to CLE through the year
December is the weak month at 63.0% on time, against 90.7% 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, Wednesday is the strongest day at 83.9% on time and Tuesday the weakest at 71.8%, a spread of 12 points.

The worst days
Worst days for JetBlue on BOS to CLE
The latest arrival of the period was on 27 December 2025, 6 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, January, July, June and September, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 December 2025 | 6 hours 37 minutes | Carrier |
| 18 January 2026 | 5 hours 42 minutes | National Airspace System |
| 28 July 2026 | 5 hours 37 minutes | National Airspace System |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 49% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 34%Carrier
- 15%National Airspace System
- 2%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 11,157 reported delay minutes.
The largest share of delay minutes, 34%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,801 of the 11,000 delay minutes reported here.
Cancellations run at 3.43%, against 1.89% nationally. That is about 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 costs
9.9% 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 70.0% on time across 672 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 671 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 BOS to CLE
Put together: the delay figures matter less here than the 3.43% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 646 completed flights over 12 months sit behind that.
