has been consistently late every Sunday for the last month -- late by 2 hours or more. Anyone know what the problem is?

We are flying SFO-MAD on paid tix 9/1, then MAD-PRG on award tix 9/2. Of course they are separate tix and records, although I've requested AA to note the continuation in the record.

Most likely will misconnect if history is correct. Any suggestions for proactive moves we should make?
