Like right now for example, or when I tried a few weeks ago. HHonors leads you all the way through the booking process, then says the booking can't be completed due to technical difficulties. This applies both using a laptop with the IE or Firefox browsers, OR their mobile app. Last time the problem continued for several days. If I call to book by phone, I lose the 500 points for an Amex online booking. Can anyone shed light on this abysmal performance, and any workarounds?
