bigger seats and I am all for that.
I think a 20% increase is a good thing. . .I would pay 20% more to ensure a less crowded jet. . .but then again, (not bragging), I only fly First because I refuse to be squeezed between the obnoxious and the smelly travelers that don't know, or respect, the unwritten rules of flying. See Up in the Air movie for a idea about what I am referring to. I value my comfort over saving a few bucks.
I travel over 150K a year, and I have seen what flies in the back and I am not going there. Again, not bragging. Just choose to spend my money on my comfort, not my chiropractor to un-kink my back, or lawyer because I strangled some snotty undisciplined brat that kicks the back of my seat.
