I didn't know that an airport wouldn't close for wind. I assume wind restrictions are different for take-off than they are for landing? What reasons might an airline have for having different safety requirements than those of the aircraft manufacturer?
I can't answer the second half of your question, but as to the first part, airports (at least in the U.S.) don't officially close unless there is some obstruction on the runway such as snow or snow removal equipment. Other possible obstructions/problems with the runway itself might be a sudden pavement failure, such as in an earthquake, or for an aircraft accident/incident on the runway at a single-runway airport.
, we were closed for about 24 hours because of flooding on the taxiways and ramps back in 1997.
