With a reference to the article "21 Days, 18 Flights," let me add my two cents as a frequent flier, both domestic and international [Business, June 13]. The problem with U.S. carriers across the board is greed -- greed that is manifested in the parsimonious spacing between rows of seats in economy class. As a government employee, I am restricted to both economy class and U.S. carriers when flying; as a 6-foot-1-inch person I frequently am crammed into a contortion that results in barely being able to walk when I exit the aircraft.

My most recent experience was with United Airlines. I could barely squeeze my knees in front of me to begin with, and when the person in front of me reclined his seat, I felt as if I had been placed in some medieval torture chamber. Seven hours later, I staggered off the plane in London, my body aching, my head swimming because sleep on this overseas flight in this configuration was impossible.

I have written to U.S. carriers about this problem, and the answer is invariably the same: "We are competitive with everyone else." Not only is that untrue -- it doesn't make it right. It also means that whenever I can flee to a foreign carrier, I will do so. My most recent foreign-carrier flight was a dream. I actually could cross my legs in economy class.

I hope The Post's story will reach U.S. air carriers where it affects them most: their bottom line. When I pay my own money, I can assure you that I will never use them.
