Maybe next time

I plead the fifth 🙋

I never lost it

You’ll be fine, both in Japan and back home I’ve lent people my card and vice versa, the only time I ever had someone look at the name was buying something from Bic Camera. It was over 5k yen so I wanted to get the tax discount, and they looked at my passport and compared the name on my debit card.

I’d contact the airline and see what they say. I’ve been on a flight before where one of the passengers had a severe peanut allergy so there were none on board, and an announcement was made warning not to consume them during the flight.
