I took the drone with a hard case that was specifically made for a carry on (I think there's only one so far for DJIs that meet that requirement):
Going to JFK, then Edinburgh - no big deal. Coming back to JFK, no big deal, flying from JFK to CLE - they wanted to inspect the drone (lol) - and said that drones are illegal in NYC and they'll have to confiscate it.
They were pulling my leg though, but I got a little pissed haha - I said you're not taking this and selling it on ebay. The drone also got stuck in the airline carry on bin from JFK to CLE. I contacted the vendor and said it got stuck, it was supposed to fit - basically the airline carry on compartment was a little bit smaller than the advertised bin outside.
The pilot got mad at me, they sent a technician to take the bin apart and the pilot said now we'll be late for the Miami flight - thanks. I told him well that's what they get for stealing LeBron for a couple years.
I got super lucky in Edinburgh, out of 10 days, only 1 day did it rain at all - and I used that day as a sleeper.
I actually wore shorts the entire time, it was in the lower 70s. I didn't see anyone else (tourists either) doing that, most in jeans and coats - wow, lol. It was comfortable to me (considering Ohio was still in upper 80s/90s at the time).
Thanks for all the hilarious HDR feedback, I was looking for that, lol...
