I had 8 flights last weekend on my mileage run to Melbourne, Australia... and I commented to a few seat mates about the sizes of the suitcases coming on board.... and people who had 3 or 4 bags.... it is only getting worse.
I watched these same people refuse to put anything under the seat in front of them... so they were true bin hogs.
I just laughed at what people were trying to bring on the flight PVD-IAD... priceless!
