Its looks like we will have two ORD red-eyes this summer. The times will be around 11:15pm and 11:59pm. We are also adding a IAD red-eye around 10:00pm. I don't believe the second IAD has been loaded into the system yet.
It looks like PDX will be a busy place for late night outbound flights this summer.
