I had read varying things about the transfer time. Unlike United Airlines or Hyatt, points do not transfer immediately.
In order to transfer points, go the Ultimate Rewards site and choose the “Transfer to Travel Partners from the drop down menu.
You will then be prompted to enter the number of miles to be transferred. I chose to transfer 4,000 Chase Ultimate Reward points to Singapore Airlines.
After entering the number of points to be transferred, you will then be asked to confirm the transfer.
I initiated the transfer on October 7, 2016 at 1:21 AM. I noted that the miles had been transferred into my Singapore Airlines account at approximately 6:30 PM on October 7, 2016. You will be sent a confirmation email regarding your request.
It took a maximum of 17 hours for Chase Ultimate Rewards Points to transfer over to Singapore Airlines.
If you are planning to transfer Chase Ultimate Reward points to Singapore Airlines for award flights, please keep in mind that points do not transfer immediately but should transfer in less than a day.
