You stated that CO meals in Y are OK but I tend to disagree. While CO is applauded for offering "food" on domestic flights, I find that its international Y meals are the worst of the Skyteam carriers. Not only are they lacking in quantity but the quality leaves a lot to be desired.
Absolutely, the 'ok' actually reflects my very low expectations based on previous flight on US-carriers (United, Delta) and not what I'm expecting or am used to on other Skyteam carriers. Plus, as I wrote, I'm not very picky in that department (can't be in my line of work). So the quality of the food, albeit unimpressive, would not be a reason for me to avoid CO if their schedules and prices were competetive (as they are out of CGN for flights to EWR).
