Trying to book RDM-PBI via SLC and ATL... dl.com keeps showing all segments as "Not Upgrade Eligible" even though the equipment is 753's except for RDM-SLC. When playing with itineraries to reduce price (which btw when booked multi-city as RDM-SLC and SLC-PBI price drops from $621 to $281) I got it to display "Upgrade Eligible" once but then timed out. Anybody else having similar problems?
