Cons: "When a bought my ticket, I had asked in the office about WiFi. They told me that you have WiFi on the plane. I had checked this information on KLM.com and saw the same, that you have WiFi. This was the reason, why a chose KLM! Then I tried to connected on board but I couldn’t! WiFi was not available. Crew told me that they don’t know anything about it! I was disappointed and angry."
