I also have a Travelpro 25" lure for international travel (love it) and a Marquis 21" carry-on lure (almost love it - just checked it out) so this is the third part of the set . It holds a ton of stuff - my laptop, books, electronics, groceries, water, etc - and still has room. Yes, it fits easily under the seat and allows easy access to everything inside. Padded shoulder straps and durable construction. I assume it will hold up well.
