July 2023 – July 2026

Share of cancellations
Of 198 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
110 cancellations, 55.6% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
59 cancellations, 29.8% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
29 cancellations, 14.6% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
198 coded cancellations were recorded on BOS → TPA; the section appears from 50.
When it goes wrong
July 2023 – July 2026
66 min late
against a median of 6 min early
BOS → TPA has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 72 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.
Percentiles over 8,553 operations; cancelled and diverted flights are counted separately.
Will your connection be tight enough?
Layovers at TPA after arriving from BOS.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 40% | Likely to miss |
| 45 min | 26% | High risk |
| 60 min | 18% | High risk |
| 90 min | 11% | Some risk |
| 120 min | 6.8% | Some risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 2.31% of the time and diverts 0.46% of the time, which a late arrival never shows up in.
Chance of missing is the share of 8,316 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 66 minutes late (90th-percentile gate arrival delay), over 8,553 operations.
