I had a bit of a revelation as I was walking around the airport and want to put this into perspective. Comfort is relative. I have a Granite Gear Taku that is my EDC -- this bag has adjustable straps and load lifters that make the bag very comfortable (it is just too big to fit under the seat of a plane). So as I was walking around the airport with my Porter 30, wishing I could further adjust this bag, I realized that this is a very big difference between hiking backpacks and travel backpacks. If you are used to using a hiking backpack, this may not be the most comfortable bag you have ever used. That being said, I was able to breeze through security and wander around the airport while waiting for my flight without the hassle of a wheeled suitcase with a bag that was comfortable. So that is a major bonus.
