Why ORD → IND flights are cancelled

July 2023 – July 2026

What each reason means

Extreme weather1 in 63

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

220 cancellations, 69.8% of the total.

The air traffic system1 in 200

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

69 cancellations, 21.9% of the total.

The airline1 in 531

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

26 cancellations, 8.3% 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.

315 coded cancellations were recorded on ORD → IND; the section appears from 50.

Will your connection be tight enough?

Layovers at IND after arriving from ORD.

Connection buffer and chance of missing by layover length, ORD → IND arrivals
Connection time	Chance of missing	Reads as
30 min	36%	Likely to miss
45 min	20%	High risk
60 min	14%	Some risk
90 min	7.6%	Some risk
120 min	4.7%	Low 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 2.28% of the time and diverts 0.04% of the time, which a late arrival never shows up in.

Chance of missing is the share of 13,474 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 47 minutes late (90th-percentile gate arrival delay), over 13,795 operations.

Share of the delay minutes US DOT attributed to each cause for ORD → IND. Only delays of 15 minutes or more are attributed.

Late-arriving aircraft is the largest cause on ORD → IND, at 43.3%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 87.1% of the time and 9 PM–5 AM departures 70.1%.

How this route holds up in bad weather
