We have been Marriott Rewards members for well over 15 years and love it. However, one problem frequently pops up. When we are planning an overseas trip using our Marriott points and need to have the points sent to our Airling Frequent Flyer program, the airline always says that they can only hold our reservation for 48 or 72 hrs max. Marriott Rewards says it usually takes them about five days to transfer points to the airline frequent flyer program. Can Marriot do something to modify your system so that it is more in sync with the airlines?
