Yesterday I checked the fares out of SEA and PDX on Expedia leaving on June 12 one way. The flights from PDX were quite a bit cheaper with the cheapest out of SEA routing you through PDX. Go figure. The least expensive was PDX-CLT at $260 arriving at about 3 pm. Next was Delta via JFK at $266 which I chose because it arrives a couple hours earlier and the line at immigration is shorter. While I was buying my ticket the price came down to $251. Yahoo! I checked this morning and the US Air price was the same but the Delta flight went up to $256.
