What facts? There was a long delay, and the F/A's did not give out food or drink service on the ground. Those are the facts. There's also the fact that they couldn't possibly do this since they had no idea when the plane might have to immediately taxi and takeoff, and the cabin needs to be free of service items before you can do that. Therefore, no cabin service.

People were very uncomfortable? Sure. That happened to EVERYONE at EWR, not just people on CO. My girlfriend JUST avoided this exact same situation that night on NWA because I called her to warn her off, and we sat next to a JetBlue plane that didn't move for hours too. Her plane sat on the tarmac for 2.5 hours. This kind of feedback is about a subjective experience, not an objective set of facts. Some people were happy, others were not, none of it was directly CO's (or NWA's, or JetBlue's) fault, but related to weather.

Personally, I, and a number of other people around me, would have been pissed if we had gone back to the gate because of a few whiners. I needed to get to SEA if at all possible. Since we did end up getting there, I'd have to give CO a thumbs up for mission accomplished. If they had bowed to the "but I'm uncomfortable" crowd, the tone of my letter would have been different.
