Burlington to Chicago

What the Data Says About BTV to ORD

The Burlington to Chicago corridor (BTV → ORD) covers roughly 763 miles and is served by 29 carriers, based on Bureau of Transportation Statistics reporting. Across 4,842 flights in the dataset, this route posts a 79.6% on-time rate with an average delay of 96.1 minutes when flights run late. Over the most recent 24 months of BTS data, 2,131 flights were recorded on this pairing — 26 cancelled (1.2%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 29 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,842 total flights analyzed, the 79.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 96.1-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Feb 2024 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 48% on-time — a 47-point gap between best and worst recent month. For travelers evaluating the BTV to ORD route, the combination of a 79.6% on-time rate, 96.1-minute average delay, 1.2% recent cancellation rate, and 29 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
