I was able to take advantage of the United Airlines/Marriott 25% bonus points promotion earlier this year by transferring Marriott points to United Airlines miles. Is this something new this year, or is it something that happens frequently? I have been looking to see if I will be able to do it again sometime. I used 270,000 Marriott points for the 7 night Cat 1-5 and 132,000 United miles. With the 25,000 United bonus miles, I was able to gain 157,000 miles. It would be great to do that again.
Also, do any of the other airline partners do this with type of transfer bonus with Marriott?
