Part pay with Avios - why is my flight not eligible?
Hi,
I can't find any specific reference anywhere. Are there rules around what kind of flight combinations are eligible for part pay by Avios?
The specific itinerary I'm trying to buy is a LGW-BCN-LHR, with the outbound in CE (I) and the inbound in ET. All BA. It says "Sorry, you can't use Avios as part payment for these flights".
Is it a website limitation? Perhaps the call centre can help?
