Review on 40L Flight Approved Travel Backpack for Men & Women - Vancropak Expandable Carry On Backpack - Lightweight, Water Resistant Business Weekender Bag in Black by Tyrazz Abouzar

I bought this set specifically to take advantage of the new low cost airline baggage rates. I have a $15 ticket from Oakland to Phoenix. I didn't want to pay $35 one way for a 'continue'. Frontier is very specific about what a Free Personnel Item Bag is. Until you expand. and pack it up again. This bag is compatible with Frontier's bag inspection tool. I had to squeeze in, but it passed. I took it to Spirit airline's baggage control tool and it slid in easier than the borders. The straps stow well when boarding but are easy to pull out when hiking.
