I don't see how this could be coded as a weather delay. I'm 100% with the original poster on this one. yes it was the cold temperatures (weather) that caused frost on the overnight aircraft. but in the end there should have been de-icing available to get that aircraft out of the origin city. since the de-ice truck was not available due to a mechanical problem, i would have coded it as a mechanical problem, not a weather problem. i'm not sure who owns the de-icing equipment in that city as each airport operates a little bit different than the next. the station i work at Delta owns and maintains it's own de-ice trucks one primary and one as a backup. and when both of those aren't working we call another airline for a favor. but that's just the nature of a smaller station.
