Older people were having trouble walking the distance, I actually went ahead to get a wheelchair for an older lady that I didn't know because there was no one on the tarmac to assist. Very horrible experience and I fly Alaska often. Never have I ever exited the plane on the tarmac in pdx and when I complained to an Alaska worker, she told me it was normal. I fly to PDX once a month and have never exited directly on the tarmac. I will definitely look for any other airline to fly instead of Alaska from now on. I will even fly spirit airlines....that is how much I will never fly Alaska again."
