I have made two Avios bookings on BA. In each case all flights are on LATAM metal.
Each one gave me an Amadeus six character PNR starting with N. Both are visible and ticketed and I can see them on Finnair.
The first booking is recognised by LATAM and I can add it to my trips there using the normal surname and PNR code method, but the second one is not recognised as a valid 'reservation number'.
Is it because the first one is a simple round trip and the second one isn't?
The trip I have managed to add has given me a LATAM reservation code. LA then 7 digits then four letters.
Is there a way to get this LATAM reservation number from the BA booking for the other trip?
Any help appreciated.
