This deal has ended.
Through 6pm CDT 9/28, the Southwest Airlines Friends Fly Free Event is back. Book either a Las Vegas or Orlando flight and hotel package for travel between 9/8 and 1/8 for Las Vegas (9/5 - 1/8 for Orlando), and every second person flies for free. Plus, if you stay four nights or more, you'll receive an additional free night at your hotel (you'll receive every second night free in Orlando with a 4+ night stay!). You'll need to purchase your package at least five days in advance of your travel time. See the Friends Fly Free Page for additional information and exclusions (several hotels are ineligible for this promotion).
