Spent 6 days in London on business with my Aeronaut and Checkpoint Flyer. Of course I was smug going through security at SFO, just unfolding the computer sleeve of the Flyer and quickly taking the 3D Cube 3-1-1 bag out in the bin. And the Aerronaut backpack straps were invaluable while schlepping through the cavernous LHR concourses & the Heathrow Express station. My TB Packing Cubes made everything easy to retrieve, and helped me to overstuff the bag on my return. Didn't quite have room for my softshell jacket so rolled it up under the Aeronaut handle.
On the return, the flight to Dulles was 1hour late and I thought I certainly was going to miss my connection to Portland ME. All the same stuff worked in reverse. Made the flight after a run. One hint.... Take a small stuff sack to put your stuff in to go through security. I didn't have time to put everything back on. Just grabbed the stuff sack and ran.
