I bought this because it was the legal size for a check in bag on international airlines. This has lasted fine across the Atlantic and to Australia. No scuffs or rips and the zipper has held fine after all those trips (14+). It was even opened and closed by TSA security several times with no issues (though I do recommend tying the zippers together so they don't open during flight. Each and every time I had it packed to exactly 50 LBS (21k) - the weight limit on most international airlines. So it performed beautifully while fully loaded with heavy items. I typically load it with clothes, shoes, toys.

The amazing thing for me is that this soft sided luggage has outlasted 4 standard rigid side luggages. Since it is extremely lightweight, I can put it into a roller luggage for easy transportation and fill it up on the way back. It doesn't have rollers, so you'll want to rent a cart at airports. But it has not broken yet - despite being dragged, poked, crushed, even has a burn mark.

Note that it isn't impervious - I make sure to avoid pointy or sharp objects in my luggage such as an umbrella. But truly, I am amaed after all these years of owning this to still be using my original purchase on flights.
