Since when is seat saving allowed? I was told in elementary school that you can't "save seats".

These silly seat games cost time. Just pick a seat (just ONE seat) and sit in it. When people are going down the aisle saying "Is this seat taken? Is that seat taken?", the small amount of time saved by having open seating is lost.

I never see people acting like they're walking on eggshells on a train or bus. What is the deal with people on airplanes?

Just get on, sit down, and let's go!!!
