+1 for what thegasguru said. I use a TravelPro rolling cabin bag, mostly because I got it for $45.00 on closeout, but will go for the B&R when it's time to replace it. I use a large military backpack that handles packing cubes really well. The eBags Motherlode also holds an amazing amount of stuff. The
Travelon bag bungee lets me pull the backpack and cabin bag as one unit through the airport.
