If you’ve been waiting for a sign to book your next trip to the Neon Capital, this is it. Southwest Airlines just dropped a massive nationwide sale, and Las Vegas is one of the primary beneficiaries.
Using the promo code ONBOARD, travelers can snag up to 30% off base fares for travel this spring. If you have friends or family planning a visit to see you in the 702, send them this link immediately!
The Deal Details:
The Discount: Up to 30% off base fares.
Promo Code: ONBOARD
Book By: February 26, 2026 (11:59 PM PT).
Travel Window: April 7 – May 20, 2026.
Where: Valid for continental U.S. and inter-island Hawaii travel.
Why This Matters for Vegas Visitors:
Southwest remains a top choice for Harry Reid International (LAS) because they offer the most non-stop routes into the city. This 30% discount makes spring travel (perfect for pool season openings and May festivals) significantly more affordable.
Sample Fares TO Las Vegas (LAS) we’re seeing:
Los Angeles (LAX) to LAS: One-way fares starting as low as $49.
Phoenix (PHX) to LAS: Quick hops for under $55.
Denver (DEN) to LAS: Mid-range flights starting around $79.
Dallas (DAL) to LAS: Great deals for our Texas friends starting at $94.
LAS Discounts Pro-Tips:
Use the Low Fare Calendar: Tell your visitors to use Southwest’s "Low Fare Calendar." Plug in the ONBOARD code first, then search the calendar to see exactly which days the 30% discount hits the hardest.
Check Existing Bookings: Already have a friend with a flight booked for April or May? Have them check the price again with the promo code. If the price dropped, they can "Change Flight" on the Southwest app, select the same flight, and receive the difference back as a Transferable Flight Credit.
Know the New Bag Fees: Gone are the days of two free bags for everyone. For the lowest fares (Wanna Get Away), expect to pay around $35 for your first checked bag and $45 for your second.
Workaround: If you have a Southwest Rapid Rewards Credit Card or A-List status, you can still snag that first (or second) bag for free!
Points Count Too: If you have Rapid Rewards points, this code works for award bookings as well! Your points will go roughly 30% further.
The Fine Print
The discount applies to the base fare, so government taxes and fees (starting at $5.60) still apply. Travel is generally valid any day except Sundays for the continental U.S. markets.
Don't wait! These seats are limited, and once the "Wanna Get Away" buckets are full, the prices will jump back up to retail.
