Leaving from Denver (DEN)

If you're checking a bag, add time rather than cutting it close. Our Denver airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Detroit (DTW)

When to book
For a trip of 1,120 miles, booking 3–6 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.
