Price variations for last-minute bookings out of Detroit are primarily influenced by demand elasticity, the timing of the booking relative to the travel date, airline capacity, and current market trends. During peak travel seasons or major events in the city, last-minute prices can increase dramatically due to high demand. Conversely, when demand is low, travelers may find significant discounts. For example, flights from Detroit to popular destinations like New York City or Miami tend to fluctuate greatly, contingent upon whether there are major local events or holidays that might affect travel demand.
