An announcement posted on the Hilton HHonors Web site (http://www.hhonors.com) states that, as of 12:01 a.m. March 21, members were no longer be able to convert United Mileage Plus miles to HHonors points or points to miles through the Reward Exchange program.
This change to the program was made virtually without notice.
It seems probable the move was made by HHonors to protect itself against the expected hordes of Mileage Plus members who will be looking to protect their miles should United fail to emerge from bankruptcy. While the decision to implement the change effective immediately is regrettable, and serves as yet another warning to program members during these uncertain times, it is difficult to fault HHonors for protecting its own interests. There is no word on when, or if, the exchange partnership will be reinstated.
HHonors representatives have acknowledged that any transfers initiated prior to March 21 will be honored. Members can continue to Double Dip with United. If you have questions about a transfer, call HHonors customer service at (800) 548-8690.
