I was able to log on ae for a short while this afternoon. Tried to do multi-segment booking. For exactly the same cities/dates, sometimes it gives error, and sometimes comes back with a bunch of available flights. So ae is not working consistently.

Now I need to figure out how not to exceed MPM for YYZ-FRA-TPE, back to YYZ (the direct BR flight TPE-YYZ isn't the problem). If it can let me log in.
