interesting. I am moving back to PDX this week. I already have a few flights for work trips booked out of PDX but some of the itins are a bit surprising.
For example, I want to fly to ANC from PDX on 4/21 and return 4/28. There are three direct flights on AS but I can't get them to come up on my search. I tweeted DELTAAssist and they claim that not every flight by AS is codeshared. So basically i'm stuck with a 7:30 flight duration on a flight that from PDX< should only be about 3.5 hours.
Tempted just to fly AS and then have the miles credited back to DL but that is ridiculous...
