The article suggests that MacBook Pros that have not yet had the battery replaced wouldn't be be allowed on the plane. My MacBook had the battery replaced early in July. I've called TUI, and they have stated that they *will not* allow my laptop on the plane on my upcoming trip, despite the work being carried out and having documentation from Apple to prove it. I don't know how they would even check, but if it came up, I imagine it would be quite a pain to deal with at the airport.
