Quick Overview

  • Marriott Bonvoy allows you to transfer points to United MileagePlus, one of several hotel programs with this option.
  • Marriott points convert to United miles at a 3:1 ratio, meaning 3,000 Marriott Bonvoy points equal 1,000 United miles.
  • For every 60,000 Marriott points you transfer, you’ll receive an extra 10,000 United miles, totaling 30,000 miles for a 60,000-point transfer.
  • Transferring Marriott points to United is valuable for MileagePlus sweet spots, especially with the Marriott transfer bonus.
