I was going to buy the Rick Steve's 2 wheel rolling suitcase at over 6 lbs. But it is 20 x 13.5 x 9.
This one from Eagle Creek is only 5 lb 13 oz and i have 2 more inches (and it says that includes the wheels). It does cost $70 more, but I could get a 10% discount. I am flying Delta the entire way. Only one flight from naples to Rome and that's also Delta. Their luggage restrictions are 22 x 14 x 9. So, is there any other reason not to purchase this except if I wanted to fly european airlines? I just think the extra 2 inches would make a world of difference for me.
