Why Choose a Backpack for Air Travel?
Benefits of Using a Backpack for Air Travel
Backpacks offer superior mobility compared to suitcases, avoiding checked bag fees ($30–$60 per flight), navigating cobblestone streets, and fitting in overhead bins or under seats, as noted by Geoff Grisdale of One Bag Travels. They suit international flights, train travel, city hopping, or weekend getaways, perfect for light packers, digital nomads, or adventure travelers. Advancements include clamshell openings, padded laptop sleeves, water-resistant recycled materials, and adjustable harness systems for comfort. Most airlines allow carry-ons up to 22 x 14 x 9 inches, though budget carriers like Ryanair enforce stricter 18 x 14 x 8-inch personal-item limits.
