✈️ Flight Guide: Austin (AUS) → Las Vegas (LAS)

May brings a mix of conventions, sports events, and concerts that can affect AUS-LAS demand. In Austin, graduation ceremonies and regional conferences can increase departures from Austin-Bergstrom International Airport (AUS), while Las Vegas hosts trade shows, combat sports events, and music residencies—driving arrivals into Harry Reid International Airport (LAS). Check event calendars for both cities before booking May flights and consider shifting travel by a day or two to avoid peak surges.

For May travel, fly midweek (Tuesday–Thursday) and aim for early-morning departures from Austin-Bergstrom International Airport (AUS) to avoid afternoon thunderstorms and to arrive in Las Vegas earlier in the day. Book 3–8 weeks ahead to capture the best domestic fares for May, and avoid last weekend of May (Memorial Day) when prices and crowds surge. If you want lowest fares, search for flights departing in the first half of May or midweek outside holiday windows.

Nonstop flights from Austin-Bergstrom International Airport (AUS) to Harry Reid International Airport (LAS) offer the fastest travel time (about 2 hours 40 minutes–3 hours) and are the most convenient during May. Connecting flights may save money—especially with low-cost carriers or off-peak times—but add connection risk and travel time. If you prioritize arrival time and minimal hassle for a Vegas getaway, choose nonstop; if you prioritize price and don’t mind a layover, compare one-stop itineraries via Dallas, Phoenix, or Denver.

Major carriers typically serving Austin-Bergstrom International Airport (AUS) to Harry Reid International Airport (LAS) in May include Southwest Airlines, American Airlines, Delta Air Lines, and occasionally low-cost carriers like Spirit or Frontier. Southwest often provides multiple daily nonstops with two free checked bags, which can be a major value for leisure travelers. Legacy carriers like American and Delta may offer more frequent early-morning or late-evening schedule options and loyalty benefits. Compare total trip cost (fares + bag fees) and seat selection fees before booking, and use airline-specific fare calendars to find May deals.

May weather: Austin typically warms in May with afternoon thunderstorms possible, while Las Vegas is warm and dry—pack light layers and sun protection. For Austin departures, allow buffer time for afternoon storm disruptions; for Las Vegas arrivals, book transfers early if arriving during popular showtimes. Carry essential documents and check airline notifications for last-minute schedule changes. Use primary keywords like 'Austin to Las Vegas flights May' when searching for deals.

Average nonstop flight time from Austin-Bergstrom International Airport (AUS) to Harry Reid International Airport (LAS) is roughly 2 hours 40 minutes to 3 hours depending on winds and routing. Early morning and late-night flights may be slightly faster with lighter air traffic.

If you don’t find a convenient nonstop, one-stop itineraries via Denver, Dallas, or Phoenix add 1–3 hours of connection time.

To find cheap Austin to Las Vegas flights in May, search 4–8 weeks before departure for the best balance of availability and pricing.
