Some tips on giving digital privacy/security advice: if you tell people they absolutely need to do a long list of difficult and expensive things before they travel, people will nod and smile and then not do it at all. This is why my advice focuses on harm reduction and understanding trade-offs.

@evacide my suggestion is print your tickets and find/keep a dead, wiped and screen-bashed smartphone in your travel bag if/when asked to show it... "oopsies i dropped it sorry".

hide the rest of your devices in your luggage.

(no i am not a security professional)

@melioristicmarie Have you ever actually done this?
@evacide @melioristicmarie I don't do this exactly, but I carry a spicy phone and normal phone. Spicy phone is more annoying to open and stays off if I expect to interact with law enforcement or TSA.
