Airlines on this route
Delta Air Lines flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another.

See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from Detroit (DTW)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Detroit airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Allentown (ABE)

Check Allentown to Detroit fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 424 miles, booking 2–4 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- Get to the airport two hours before departure; security, not the flight, is the part that runs late.
- If you're traveling with only a carry-on, you can skip the bag-drop line entirely with mobile check-in.
- Download the airline's app before you fly; gate changes and delays show up there first.
- Nonstop time on this route is about 1h 22m — a one-stop itinerary needs to be a lot cheaper to be worth the extra hours.
- Tuesday and Wednesday departures are typically the cheapest days on domestic routes.
