Allentown/Bethlehem/Easton to Detroit

What the Data Says About ABE to DTW

The Allentown/Bethlehem/Easton to Detroit corridor (ABE → DTW) covers roughly 425 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 2,011 flights in the dataset, this route posts a 90.2% on-time rate with an average delay of 107.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,568 flights were recorded on this pairing — 23 cancelled (1.5%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,011 total flights analyzed, the 90.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 107.7-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, Nov 2020 posted the best performance on this corridor at 98% on-time, while Jul 2021 came in at 77% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the ABE to DTW route, the combination of a 90.2% on-time rate, 107.7-minute average delay, 1.5% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
