Any experience on how quickly the XP post currently? I only linked my account last week, and they don't post XP for my Novotel stay back in March. Still planning to go the Athens. I am looking to try a mixed class AF/KLM ticket (going: business via CDG, return: eco KLM direct) for a favorable price. There is 10 days between the outgoing and incoming flights. The trip to Athens would give me 60XP, I already got 30. Wondering if I can make it to FB Silver for a year and try out the privileges that come with it. So if I stay at a Accor property the first 3 days of my trip (have to be somewhere else in Greece for the last 7), does that post quickly enough to buy a 'eco light' ticket for the return and enjoy the additional bag privilege of Silver?
