Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.

497 cancellations, 78.4% of the total.

The airline1 in 196

Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.

103 cancellations, 16.2% of the total.

The air traffic system1 in 593

Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.

34 cancellations, 5.4% of the total.

Security—

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.

DFW → LGA has an average that understates its risk: a typical arrival is 4 min early, but the worst tenth are 68 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 20,151 operations; cancelled and diverted flights are counted separately.

Will your connection be tight enough?

Layovers at LGA after arriving from DFW.

Connection buffer and chance of missing by layover length, DFW → LGA arrivals
Connection time	Chance of missing	Reads as

45 min	26%	High risk
60 min	19%	High risk
90 min	11%	Some risk
120 min	6.5%	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 3.15% of the time and diverts 0.98% of the time, which a late arrival never shows up in.

Chance of missing is the share of 19,320 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 64 minutes late (90th-percentile gate arrival delay), over 20,151 operations.
