AF / KL combined fares
I have just booked a flight Y class AMS - BKK - CDG - AMS.
First I went to the KLM website where for my travel dates they only showed KL flights for a fare of > € 850.
Secondly I tried the AF site where for my travel dates they only showed AF flights for a fare of > € 750.
Finally, via ebookers.nl I found a fare outbound on KL back on AF for around € 620.
So it seems the combined fares are available on (some) travel agents' sites, but not (yet?) on the KL and AF sites.
