Flew into Vegas Feb 21 with plans to get married on 25th. Pleasantly surprised when we stepped off the plane to find that we could get our marriage certificate at the airport instead of having to make an extra trip to the location downtown. No line at all which was great! As an added bonus, the airlines have a promotion for a free bottle of champagne to couples that get their certificate at the airport. Southwest will also upgrade your return flight to A boarding. Had not seen this mentioned here, so just wanted to pass it along.
