Cheap Flights From Detroit (DTW) to Houston (IAH)

Use flexible dates to compare fares across multiple days and departure times. Midweek flights are often cheaper, and booking a few weeks in advance can help you secure lower prices.

A nonstop flight typically takes around 3 hours. Connecting flights may take longer depending on the layover city and wait time.

Booking 3–6 weeks before departure often gives you access to better fares. Traveling during off-peak months like September or late January can also help you find lower prices.

The best deals are usually available during midweek departures and outside major holidays. Setting fare alerts helps you track price drops and book at the right time.

Compare total prices not just base fares including baggage fees and seat selection costs. Filtering by nonstop or preferred travel times can also help you find the most convenient option within your budget.

Round-trip fares are often cheaper overall, but comparing both options can sometimes uncover savings. Mixing two one-way tickets on different airlines may also reduce costs.

You can typically pay using major credit or debit cards. Some bookings may also support digital payment options, depending on availability at checkout.

Most airlines allow changes or cancellations, but fees and eligibility depend on the fare type you selected. Always review the fare rules before completing your booking.

Basic economy fares may only include a personal item. Carry-on and checked baggage usually cost extra, so reviewing baggage policies in advance helps avoid surprise charges.

Customer support can assist with booking changes, payment questions, or travel updates. Keep your booking reference handy for faster service.
