Still not able to transfer over Midwest booking to profile on F9 under MM account.
The following message comes up, after entering PNR:
A 50x server error was received attempting to serve your request, indicating that either the server is currently unable to handle the request or the request timed out waiting for a response. The error may have been due to a temporary issue and therefore you could try to access the web address again.
I can view the same itinerary, however, under the ER account, with the F9 PNR.
