Besides more miles for card spending (I have many more than I need right now), doesn't the value of the Delta Business Reserve Card drop precipitously after achieving Diamond Status? I achieved diamond status quickly this year because of high MQM rollovers to MQDs. Since MQDs do not rollover into next year, would it not make more sense to switch to another card to spend on for the remainder of the year? For example, I also have a Bank of America Travelers Credit Card which earns 1.75 miles per dollar spent because of my platinum status there. It seems to make more sense to move all my spending there since those points can be used widely for any airline, hotel, or other benefits, while there are no more benefits to be had using the Delta Business reserve card once Diamond, the highest status, is achieved. Then in 2025 I would move my spending back to the Delta Card until achieving status, and then do the same thing. Does this logic make sense or am I missing something? Thanks.
