Here's a question I haven't found the answer to : do aircraft carrier have like an IATA/ICAO airport code ? If you fly your C2 from Chania to say the Roosevelt, your origin would be CHQ/LGSA what's the destination code ? I think that by rubber-ducking it like this I found a possible answer : CVN71, the hull number.

So here that would be : CVN69 as origin and MCT or FJR as destination.
