I have had success linking my travel accounts (ie Marriott rewards) but afterwards they are not available in the accounts section. Having another sheet to track all available reward points would be very beneficial.
Are you looking for a sheet that you can manage yourself and manually update the rewards points each time you get a statement?
This can be useful to know your total points and see where you have the most points. Plus, know if some points are about to expire.
Or, were you looking for something that automatically updates the reward points. The Tiller Feeds don’t receive any information about reward points (to my best knowledge.)
