Thanks LondonAndy,
yes, I put the same question on both Staralliance and Skyteam forums. It's not my intention to disregard rules, I only want to have a FFP for every alliance (my Eurobonus is about to expire) and so I put the question on both forums. In other words, for every alliance I wanted to subscribe the one that has the most comprehensive website to book partner flights (among other things that I'll individually evaluate)
