I booked with Propeller travel a BA multi city route with the outbound on AA metal (AA39) but booked on BA codeshare (BA1528). This booking contained a checked bag allowance and the agency have re-confirmed this with BA partner support.
All is fine and as expected on the BA website:
When I load it up on AA though it tells me we that it is a basic economy fare and checked bags are extra. This is bizarre because this warning has appeared long after booking - I selected seats for free a few months back, when no such Basic Economy warning was displayed.
I have a clear audit trail with the travel agency that I booked a fare including checked bags. However, I'm acutely aware that they have no power when I walk up to the AA desks to drop my bags on the date of my flight.
Can anyone advise on what's likely to happen here and what, if anything, I should do?
