Wanted to book an 'easy' oneway award today:

As usual, GRU-BRU didn't return any availability on the M&M site but GRU-MUC did in F and there were plenty of options between MUC-BRU in C too. I was quite surprised the M&M agent told me I was not allowed to combine this availability in one award ticket. She would have to book both segments as separate tickets. (And thus more miles would be required)

Didn't realize the extra Senator award availability is limited this way. Any advice how to handle this one? Book the GRU-MUC in F and keep checking afterwards until M&M releases the GRU-MUC-BRU availability? In worst case, I buy MUC-BRU as revenue ticket. Thanks.
