I spent the summer in London. I had no overnight trips planned and since I was staying in the same place for two and a half months, decided to bring a larger suitcase. (25").
Trying to maneuver this heavy, four wheeled monster, from airport to tube to hotel and back was a nightmare. (I dragged it on two wheels about half the time.) I put my "personal item" on top to make moving easier but that just caused the whole thing to fall forward and make it difficult to steer on anything but smooth floors.
Upon arriving back in the U.S., I was one of the first at Global Entry and it was only ten minutes from the time I walked off the plane to the time I handed in my slip at the combined immigration/customs desk.
Ten minutes and I was free to go. Free to position myself at the baggage carousel. I watched everyone else with just carry on sail right past me on their way out of the airport. They way I had done for many years.
But this time I had to wait. And wait. And wait. Twenty minutes later the bags arrived. In twenty minutes I could have been at my hotel.
The sad part is, if there is only one, I wound up using only half the stuff I brought anyway--an amount that would have fit in a carry on.
In the future, If for any reason I have to bring more than I can fit in a carry on, I'll ship it.
If you like checking heavier bags, more power to you. As for me, I'll stick with what can fit in the overhead.
Anyone else have similar experiences or revelations?
