I am just under 10k delta sky miles away from a flight for my wife and I. I am considering using the Marriott rewards feature to convert 30k Marriott rewards points to 10k delta sky miles. I have never done this before because the conversion isn't great but I think it makes sense to me in this instance. My question is if anyone is familiar with how long the "order" takes for the sky miles to appear in my account? I do not want to place the sky miles order if it is going to take a significant amount of time and risk the award travel rate to jump up, thus wasting the conversion. Hoping someone has experience. Thanks for your help in advance.
