Has anyone managed to get the Multi City option work when booking on either AA on Amadeus or AA American UK. I keep trying but have not succeeded. American UK displays an error - typically this seems to be that the fare is no longer available - it then shows different suggested itineraries which has fewer stops i.e. a more direct route. Typically the fare is nothing like the fare you were searching for.
AA Amadeus displays the routing and prices in euros but after you have entered all the passenger details it displays an error - typically 15012.
The only time I can seem to get ITA Powertools booking links to work is when doing a round trip with American (works nearly all the time) or BA (works some of the time)
