noob here. Love the site! I have a current first class reward ticket on CO using the min. miles (25,000) from IAH to SEA, then flying back from YVR to IAH. The IAH to SEA leg is actually on US (ugh) flying through PHX, as no saverpass tickets are available for any CO direct flight.
My question is there is no first class seats sold on several CO direct flights, but it says reward tickets aren't available. Can I get on a "waitlist" for these seats? I have about 4 days left before the 21 day threshold.
