Hmm, I must admit I'm a bit surprised to read this. Not doubting you MD, but over the years I have found the Swedish CAA to be quite swift and easy to work with. Maybe I've just been lucky.
Switching to a UK license sounds like it would be a lot of work for something I don't necessarily need at the moment as I'm (thankfully) flying on my FAA license. What would be the process of doing this switch?
