My United account has been slow. Even slower
my AA and the "new" website (it takes about
2-3 weeks to get that up to date.) Also
Westin has a tendency to be slow with putting
the latest information in, but they have
nicely apologized when I asked.

To keep track of my miles (with my short term
memory) I have in my computer software MAXMILES (which I think Randy recommends.)
I put the information into each of the airline and hotel accounts immediately when it happens and then just check it off when
I get the printed statement.

Maxmiles might be worth a try. It's like
TurboTax and other budget like programs.
