How Much Do Cheap Flights From Detroit Cost in 2026?

Budget airlines dominate Detroit's cheapest routes, but prices vary significantly by airline and booking window. Spirit (NK) offers DTW→MSP for $78 on March 12, 2026, while Delta (DL) charges $112 for the same route with one free checked bag included. Frontier (F9) provides DTW→Miami (MIA) for $89, which includes a 20kg checked bag – a rarity among budget carriers on this route. I paid $92 for a DTW→MIA Spirit flight on March 15, 2025, after booking 45 days in advance. Prices range from $78 to $142 one-way depending on demand and baggage fees.

Watch Out For: Hidden Fees on Budget Flights

Spirit Airlines' base fare excludes all checked bags, adding $30 for 15kg on DTW→MSP routes – a fee not visible during initial search. I learned this the hard way when my $112 Spirit ticket became $142 at the airport in 2025. Booking.com also adds a 14.5% "taxes and fees" surcharge not shown in headline prices, increasing a $100 flight to $114.50. Always check the final price before payment.
