Changes are a comin' at major airlines, you can be sure, in the USA.
One recent example, Southwest at RNO.
The airplane diverted to OAK due to a reported brief heavy snowfall and high winds on approach...and several pax were wondering why.
RNO is (or can be) a very challanging airport in the wintertime, and I suspect that Southwest learned their lesson well at Midway, when they slid off the end into a passing auto, and killed a child.
The FAA is clamping down, and I hope it continues.
