OK fine, take the 5 bucks. She then transferred me to the "Payment Center" which is closed in the middle of business hours.
Tried this twice already at different times of the day with the same outcome.

The funny thing is, when I pull up my rez on MS's site, it now says I have my preferred seat assigned and a $5 fee was paid!
Any advice?
We're traveling separately into FRA so it would be very nice to sit together on that last 4 hour ride.
