Delay causes
Why DL 1098 runs late
Late-arriving aircraft accounts for 62% of the 7,544 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 22%Carrier
- 15%National Airspace System
- 0%Extreme weather
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,544 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 7,544 delay minutes reported on DL 1098.
Cancellations sit at 1.11% against a national 1.89%, which is ordinary. Diversions add another 0.56%.
Connections and routes
What a delay on this flight costs
11.3% 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 1,124 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.
Every one of the 360 flights under DL 1098 in the data flew BOS to MSP. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 360 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.
