My brother has a 6:30 AM flight out of LAS. I checked the WAX schedule and the first bus doesn't leave until 5.20 AM from Casino Center & Fremont and wouldn't get to McCarren until 5:45 AM. Even at that time, that is cutting it too close. He is staying at MSS. Besides a cab, what are his bus options and where would he catch it near MSS? Pre-purchased tickets required, etc. He is thrifty, so cab is probably the last resort. Except for the WAX, I know nothing about the bus system. Thanks for any help!
