Get ont he waitlist!!! If you get on the waitlist, sometimes they search for waitlists inside 5 days and release those seats. Especially since you already have a Saver seat and your not a skychoice looking for a saver.
Makes sence to us but, then again . . . they might be trying to get you to splurdge an extra 100,000 miles for the choice reward?!?!?!
