Southwest is a must for most all frequent travelers. Get in, Get Out...get on with it.
The non-assigned seating gives "bigger" guys like me a glimmer of hope when it comes to not getting pinned in a middle seat for even the shortest of flights. And knowing that my bag will fly free...helps the bottom line A LOT.
The staff here in Vegas is always helpful and friendly,,,even at those late, Las Vegas hours.
