About 4 years ago, my son was set to come home from college in Portland and it had snowed about an inch the night before. His ride to the airport cancelled, no Uber or Lyft was working, mass transit was out and the roads were blocked by cars abandoned. Still the airline said the flight was on schedule.I asked if they planned on having any passengers since nobody had a way to get to the airport.
Airline wanted 200 bucks to change his flight. I waited a half hour, called them and I got somebody with a heart and common sense. Changed the flight for 22 bucks.
Bottom Line: Portland has zero ability to handle snow, some airline people are nice!
