Okay - may seem like a silly question - please bear with me! The majority of my flights over the past 5 years have been only with carry-on luggage (about 85%) only. The other times, I have brought my checked luggage into the long snaking line at the Airline counter inside the airport. So here's my questions - I have never used the curbside service at any airport, let alone McCarran. How does it work? Are the people that help you called Skycaps? Where is it located? Is the line generally less than the indoor line up? Can they print boarding passes? Customary tip (for one bag)? This is my situation - Allegiant Air - I have a seat assignment, so can print out boarding pass at hotel before I get to airport (NOTE: Allegiant Air is not included on the kiosks at the airport!!!). I arrive at airport at 6:00 a.m. - heard that line ups can be ridiculous at that time - basically I don't want to cut it too close and have too much stress waiting in lines.
