Air France / KLM have changed the validity period of bonus miles from 36 to 20 months without notification. I did not receive any email, SMS or phone call for this subject. That's why I thought I had enough time to use them. But when I tried to do so some months ago, I saw I had no bonus miles in my account. Very surprising. I asked for a correction, but they refused it. Not sure what was the reason. I dont trust those two companies anymore.And I am not going to fly with either Air France or KLM. I would like to warn people to think twice before use them. read full review »
