I don’t know very much about Sub-GHz or airport security but I believe that having a device with a bunch of antenna could be suspicious. So given that you have your flipper turned off during xray and other security checks, would you be stopped and have a risk of it being confiscated? While it would be really cool to take the flipper on holiday to capture lots of new data, I would not like to risk losing it for obvious reasons.
A lot of people had already flown with their flippers and had no problems
Ok, thank you!
