Flights from Detroit to Austin

Compare Detroit to Austin flights the smart way

Booking Detroit (DTW) to Austin (AUS) doesn't have to mean opening a dozen tabs.

You pick the deal that fits and book it directly with the provider. We never add a booking fee.

Tips for a cheaper DTW–AUS fare

• Be flexible with dates. Mid-week departures are routinely cheaper than Friday or Sunday flights on this route.
• Compare one-way pairs. Two one-ways on different airlines can undercut a round trip — checking both takes seconds here.
• Watch the baggage. A cheap basic fare plus paid bags can cost more than a standard fare with luggage included; every FareKite result shows the fare's baggage note.
• Ask about phone fares. Some partner agencies hold unpublished fares that never appear online — worth a quick call for complex or last-minute trips.
