My wife and I recently had a Friday 6:00 a.m. flight out of LAS on Delta. We figured we would sail through baggage check-in with no trouble so early in the morning. Boy were we wrong. We got to the airport at about 4:15 a.m. and even at that hour, the Delta baggage check-in line wrapped all the way through the cordoned-off area. It was "rush hour" packed, and it's a miracle we got to our gate in time. I don't know if Delta is this crowded every morning, but just a heads up for fellow Delta flyers—if you're checking bags, that "arrive two hours prior to departure" rule applies no matter how early your flight. We won't make the same mistake twice!
