Earlier today, I attempted to book a multi-city itinerary that I had saved on Google Flights (which included a nonstop leg from PDX to ORD). However, on aa.com, I was unable to book it, and the AA site was acting rather weird. Tonight, I checked again, and it looks like there are now no nonstop PDX-ORD flights Nov 5 - 15, Nov 23, and Dec 20 - Jan 7. Is this just some kind of data hiccup, or is it possible that they have actually cancelled those particular flights?
