No ifs; it did. There are risks to a once-a-week flight in that if it cancels, then choices are limited, but there are choices.
Some do that: park on the US side, walk across a special bridge to enter the airport, etc. I think those flights connect in Mexico City, without English subtitles to signs and announcements, and getting stuck there would be challenging.
Ha! Weather changes faster than a woman's moods.
That's the easy part.
Taking off and landing in storms is what's dangerous. In worst cases, the airline remove the planes empty before the worst storms hit and hide them elsewhere, but in marginal cases, you do not want to be on a plane that might make it on a bad weather takeoff attempt if the plane did manage to land in the storm.
