Sometimes use them http://www.airporter.com for trips from Seattle to Yakima when driving doesn't seem a good option, because they don't smell as bad as a Greyhound, and the passengers are a little less sketchy. If you get one of their smaller shuttles instead of a bus, the seats are more comfortable than those of a Greyhound bus. The ride takes an hour less than 'the dog', and with airport security complications, flying 150 miles often isn't worth the hassle. But sometimes they've been as late as an hour to pick me up, so if the weather conditions are bad, don't expect much. Don't expect much from the person on their end of a phone conversation, for example my grandmother called when they were more than three hours late due to accidents on the pass and their agent said that I had arrived hours ago and that the driver was already in bed -- I was still in Ellensburg. So in ideal weather conditions, they are better than 'the dog' but otherwise don't bother going with them over the pass because they will mess up often and sometimes in very annoying ways.
