Now, I have discovered, on a forthcoming flight, I have been moved from seat 6A in the middle of the plane to 10A, right next to the bar and the toilet, because the aircraft has been changed. Listen. I know that in the grand scale of things, these are not major life problems. But I spend a lot of money with the airline and, after my sixth unanswered e-mail addressed to Customer Service about many other matters, am mightily fed up with the time and energy I constantly have to waste trying to get even a modicum of service at ground level.
