Do you think you will use the companion cert with the reserve? The last time I did it was for FC tickets for vacation that had a price of 1100 a seat so greater than the annual fee in benifets since I got one ticket for free. I have the unbranded plat and the delta reserve for
me and my wife has one to for double the companion tickets. I value we come out ahead despite the fees.
All the tickets go on the plat for 5x. Things I have no bonus on goes through the reserve until I hit the boost spending requirements. I also do pay with miles often so we still get the mqms but cheaper FC tickets.
