Frontier and Spirit have round-trip flights from Houston (IAH) to Denver or Las Vegas (DEN/LAS) for $51-$59, NONSTOP. Denver flights March to April. Las Vegas flights March to May. No Sunday departures. Very few weekends available. Origin/Destination reversible.
To clarify: Denver Spirit fares begin after mid-April otherwise it’s flying on Frontier. There are no discount Spirit fares for Las Vegas; Frontier only.
You can also save an additional 16% off your Hotel or up to $150 for Flight+Hotel packages on CheapTickets by using the “WANDERLUST” or “ADVENTURE150” coupon codes at checkout (before finalizing your booking).
Note: Frontier and Spirit fares do not include a free carry-on bag. Only a small personal item, like a Jansport City Scout backpack is free. You can avoid paying for seat selection if you accept the randomly assigned seat prior to boarding.
Note: Frontier and Spirit seats only have 28-inches of pitch; 2-to-3 inches less space than most other airlines.
