I keep my documents in my wife's panties.

Secure. Even I have trouble accessing them.

R/T endorsement is required under ICAO and if you are ramp checked overseas the Inspector will ask for it.

U.S. Airman Certificates don't include the R/T endorsement and also they only state "English Proficient." The latter means you possess Level 4 proficiency which according to ICAO guidelines must be renewed every 4 years. Additionally, U.S. certificates have no expiration dates and there is no way of proving that you are current on the aircraft you are flying by looking at of your certificate.

So if you fly internationally it will be a good idea to have the FCC license and your proficiency details (sim check form, line check details etc).

I carry a passport wallet in my pocket. It has slots for cards where I put my FCC etc. Another pocket with my medical inside of it. I keep it with me ever since I left it in my flight bag when I was trying to JS home. Makes it easy to get when going through global entry!

Not bothering with proficiency details. Do you also carry around your logbooks to prove that you've done 3 landings within the last 90 days?

Passport, FCC license, and medical all sit in my EFB sleeve in the front pouch. Pilots license sits with my drivers license in my wallet.

Oh...gosh. Imagine that, pilots put their docs exactly where you'd expect. Who are you, that idiot Don Lemon from CNN? No story here homie.

This Passport wallet allows me to keep all my docs aside from my company ID together.

I have a tiny wallet that I keep my licenses, medical and FCC permit in. I keep that wallet in my flight kit next to my passport. If I have that little wallet, I have everything I need.

I haven't but I know that some pilots, especially those flying overseas do so.

Haha you beat me to it. Not sure where else we could keep our documents besides our wallet or luggage.
