I am fairly seasoned. I am usually pretty smart. This time, I fell to the trap. The trap based on FCM.
I know that RU inventory is released at different times. I did not think it applied to Y class fares.
I just booked a trip with my return segments being on Y class. Segment 2 upgraded but 1 did not. I called and they said there is no availability (but 6 seats available in first).
The wording on this page:
https://www.delta.com/content/www/en...-upgrades.html suggests under Priority 1, all Y class get upgraded at time of ticketing. Priority 2 and 3 are what we all know as UG priority yet do not even include Y in the fare class list.
It is not clearly stated about Y class but it was explained to me that all 'Unlimited Complimentary Upgrades' are based on the T&C below on that page that limit the UGs to 'Availability' of the 'R' fare and inventory.
I know I have zero leg to stand on. Do I?
