I use this for business travel for 5+ years. Great for carry-on in the USA can go overhead or under the seat even when full. I also use this to travel to China with 2 weeks of clothes (packing experts only). Comfortable for broad shoulders, but cannot remove/put away the hip belt when using the shoulder straps which gets in the way (must always fold them under after mounting the pack). The outside water bottle holders don't work for me when the pack is full. The metal frame is wonderful and is very comfortable on my back. The zippers have held up under stress, but they always feel subpar compared to my other packs with premium YKK zippers that seem to get better with use. Overall I recommend this pack for airline travel, but the fact Osprey has not updated this pack over the years means I will pass on it when my current one wears out (starting to wear out now with material rips).
