I have had several flights out of and back to PAE recently, all were great. It does take a bit for the Lyft/Uber drivers to get to you as their holding area is well offsite, but you can wait inside the last building adjacent to the ride share pickup point. Alaska even treated PAE as a co-terminal with SEA from PDX the other night when there was a 1 hr 22 min ATC delay. They called for anyone that could fly to PAE instead of SEA that wanted to get out quickly (I did!) even taking those that had checked bags. (they pulled the checked bags and moved them to the PAE flight) With the new Hwy 99 tunnel getting to and from SEA is really quick for me, but so is PAE, so it is a great option when on flights using the E175s.
