Frontier and Spirit have round-trip flights from Austin (AUS) to Las Vegas (LAS) for $47-$58, NONSTOP. Flights August to September. Extended weekends available. Origin/Destination reversible.
Some small OTAs on Skyscanner have this for cheaper than the airline ($35). If you plan on booking there, beware of any site that charges a fee to cancel a ticket within the 24-hour “free” period. Use unknown booking sites at your own risk.
Frontier fares do not include a free carry-on bag. Only a small personal item, like a Jansport SuperBreak backpack is free. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
Frontier seats only have 28-inches of pitch; 2-to-3 inches less space than most other airlines.
