Don’t wait -- book your Fall trip today & save big! I just came across this offer this morning. I was able to save over $100 on airfare for my wife and myself on our return flight from Vegas for our August trip (our trip is from Aug. 11-16 and our departure isn't within the sale). Plus, we came in under the 50,000 points we received for signing up for the Southwest Visa Card. All in all, we saved about $800 in using Southwest Visa Card promotion! And we got one free night at the Cosmo in a Terrace One Bedroom Fountain view and saved another $200 using the Vegas.com gift cards that we purchased from Costco.
