Detroit to Allentown/Bethlehem/Easton

What the Data Says About DTW to ABE

The Detroit to Allentown/Bethlehem/Easton corridor (DTW → ABE) 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 90.5% on-time rate with an average delay of 70.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,568 flights were recorded on this pairing — 22 cancelled (1.4%) and 5 diverted (0.3%). 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 90.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.4-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, Jan 2021 posted the best performance on this corridor at 100% on-time, while Dec 2020 came in at 81% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the DTW to ABE route, the combination of a 90.5% on-time rate, 70.4-minute average delay, 1.4% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
