The annoying thing in my case is that my new itinerary includes an overnight in PDX where there was previously none (EWR-SEA-ANC became EWR-PDX(overnight)-SEA-ANC). I'm trying to get rebooked on another airline to get me to SEA before my originally scheduled SEA-ANC departs, but my first attempt got disconnected before someone picked up. Let's see how well this attempt goes.
