Booking issue:
Anerican Airlines: Trying to book: A==>B, B==>C on same day, same airline (i.e. connecting flight, one way ticket) - trying to book as a MultiCity ticket - it prices out MUCH cheaper than a one way ticket, but won't actually complete booking. The lower price is also visible on Matrix, but not able to book on OTA either.
Any ideas on how to make this happen on the AA site or an OTA?
