"Charging $3 for water doesn't seem like a reasonable thing to do, regardless of increasing fuel prices or competition from other airlines. I usually bring my own water on planes, but this offends me on a fundamental level."

Wow. If your offended by that, then really--hole yourself up in a closet. These so called "bloggers" post excoriating reviews about having to pay for bottled water on an aircraft. Is it an entitlement? Of course, they are probably from the generation where everyone gets a trophy mentality. I fail to see any of these bloggers compalin about the cost of ammenities like bottled water at a sporting event. Try going to a NFL or NBA game and telling the concession stand "I paid good money for this ticket, I deserve a free bottle of water." I went to the Ryder Cup last year and paid well over that for a bottle of water.
