What is the most popular airline to fly into Detroit?
Detroit Metro Airport is a hub for Northwest (and Northwest’s code share partner KLM), and Northwest offers far more flights in and out of Detroit than any other carrier. If you’re looking for a seat, it’s probably easiest to check for Northwest availability. If you’re looking to maximize mileage on Northwest (or any other airline, for that matter) for free tickets home or vacation trips, see the Mileage Workshop. Note that Sprint long distance and Sprint PCS offer Northwest World Perks miles based on usage.
