Is this a post retirement question or a career change question?
if it’s a post retirement question I intend to never set foot anywhere near an aircraft or an airport ever again unless I absolutely have to. I’m currently looking at what to do with my significant increase in spare time I’m about to get (tied in with my imminent start of part time work). Several ideas are tickling my brain.
If if it’s a career change question, personlly I’d go back to logistics which is an area I had a career in before flying.
