Southwest Airlines, by far, carries the most passengers in and out of Las Vegas. In 2004, of the 41.4 million passengers who got off and on airplanes at McCarran, roughly 13 million of them were carried by Southwest (nearly a third). It doesn’t matter how you average them -- daily, weekly, monthly, annually -- SWA wins the contest, hands down.
Its nearest competitor, America West, transported approximately half as many passengers -- 6,828,903 -- in 2004. The other three "top-fivers" were United (3,186,979), Delta (2,780,046), and American (2,594,439).
I have a question I can't find a clear answer to. As a foreigner, what's the easiest way to deposit cash in Vegas? I'm not talking about big amounts, but what if I want to deposit $500? Or $5,000? Can I open a bank account in Vegas? Can the casino wire it for you? Do they charge for this service? What if it's table game or poker money? Will the casino still perform a wire if you have the chips on you? I've only heard about this with slot jackpot. It seems like getting cash is easy enough by using an ATM or depositing front money, but I never hear about getting money back home. Not that I pretend I'm going to win, but I wonder what happens to people who do and are foreigners.
