So I am dealing with a situation now: A couple of months ago Delta loaded the schedule with 767 equipment for LAX-HNL/HNL-LAX and actually began marketing Premium Select on the route along with Delta One. The rollout was full of glitches, as one day the website would show Delta One/Premium Select and the next day it would be back to standard domestic first class and Comfort+ offerings, but still with 767 aircraft. Finally they settled down and published, once and for all, Delta One/Premium Select on the route, all three daily flights. There is actually a separate thread about that on this board.
I booked HNL-LAX-ATL on a date in September and applied a Regional Upgrade. This cleared me into Premium Select for the HNL-LAX leg and Domestic First for LAX-ATL. Ticket was issued.
A couple of weeks ago, however, Delta did a major change and switched two of the three HNL-LAX flights back to narrow body equipment (A321 Neo) marketed as Domestic First, Comfort+, and Main. When this happened, and there was no longer a Premium Select cabin, the system automatically rebooked me on an itinerary of HNL-MSP-ATL, with a 31 minute connection in MSP. However, this would not work for me.
I called in trying to get back on my original flights. What I asked for on the HNL-LAX segment was to be booked into Delta First, since I had previously been confirmed in Premium Select when that was being offered in the market. I was met with a cold hard no. I could only be rebooked in Main and waitlisted for Delta First since no upgrade inventory to use a RUC was available.
To me, in this situation, a booking in Premium Select should translate to a booking in Delta First for a domestic flight where Premium Select disappears because of an equipment change, but they wouldn't do it (even after being escalated to Global Ticketing Support). So now I am in Main waitlisted for First using the RUC.
Something about this just stinks to me.
