For twelve years, I've never checked a suitcase, always having one carry-on. Twelve years ago we took our first RS tour to celebrate our 25th anniversary....still have that old green RS roller bag and know the advantages of packing light.
Well, my business trip this month to Florida involved a 3-hour layover in Atlanta, and a very tight connection on the way back to Seattle with the small planes that make you pick up your normal-size suitcase after un-boarding passengers. So, instead of my regular habit of using my 20" suitcase, I pulled out my old RS bag and filled it with items for the 2-week business trip.
New experience at the airport - I had to go to the section in the airport to check-in and find out where to hand-off my suitcase. Easy & no line. Then for the boarding. Do you know those crazy people who are always trying to get onto the plane ASAP? Yes, that's me...because I need to secure a spot for my suitcase. But, this time I could relax when they called the flight and let the overhead bins fill up.
When I arrived at both destinations, my bag was on the conveyor - probably because there's few checked bags now.
I definitely will continue to carry-on for any vacations, but it was interesting to experience "the hand-off".
