Had another thought, and the amount of BTC would also matter, but what about a trusted friend / relative.
Before the flight send the BTC / other crypto to a trusted person.
Remove all BTC / crypto apps from phone. (you do have a backup right???)
After flight contact trusted person and have them send it to the new address that you just generated with the wallet you just reinstalled.

You would have to trust that person, but there is also a different between beer money and vacation money and life savings money.

From the way you were talking (going through airport) I would think vacation money. And I would hope that you have friends and / or family that you could trust with that amount.
