How can such a small airport handle such large swarming crowds of sometimes drunk people? Very poorly. It's a highly traveled airport, always with tons of delays, long lines, cranky crabby people (workers and travelers) a severe shortage of seats while waiting for your flight....my head hurts just thinking of it. I dread coming to Vegas thinking of having to deal with anyone at McCarren. My suggestion is to carry-on your luggage-avoid the baggage claim and anything that would require you to spend an extra minute here. They do a decent job of herding people into the right gates but they stink as far as customer service...cracking a smile or a squeezing a hello from these peeps is like beating the house....nearly impossible in Vegas, apparently.
