Checked in at Terminal 3. Bring some Food with you if you have to wait for Ticketing. Here are no possibilities to get some serious Food before the Security Check.
Apparently there is no priority line for American in terminal D, and/or the security guy was just a total douche. So plan some extra time if you have status on American to go through the general lane
Nothing more exciting than a flight coming in to Vegas on a Friday. Everyone is a high roller. Nothing more sad and pathetic than a flight leaving on Monday. Everyone is broke and all used up.
Use the Wells Fargo ATMs at the airport before you pay crazy fees at the ATMs in the Casinos. Also $17 for a meal at airport Subway... hmm I think thats reasonable
