I did some searches and can't find anything relevant threads... but I'm sure this has been discussed before.

I've been diamond and PLAT consistently over the last few years. To be honest, I don't see my upgrade % that much better with DIA status... Since I fly almost as often internationally as I do domestically, I get lounge access anyway (I also have priority pass membership). I have no use for those upgrade certs. I do enjoy the ability to cancel award-flights without charge.

This year, I have the (good) problem of possibly going over 125K MQM. However, I would much rather keep PLAT status and roll over ~50K miles. Does anyone have any experience getting Delta to hold their status at a certain level and just roll over all the MQMs?

My MQD is already over $15K, so that isn't something I can adjust for.

Another thing is that I'm at ~110K MQM now, and the possible flight is to China in business class, so that is going to be ~20K miles MQM. I can't get creative and book the ticket as 2 1-way. It is all or nothing... I have no status with any other airlines, so I'd rather not fly another airline unless it is for the sole purpose of not gaining Diamond status at Delta.
