My son was on a flight this week and dropped his iphone down in the seat 20 minutes before landing. He tried to retrieve it when they landed and was told by FAs he had to leave it and clear the plane because they had such a tight turnaround. Find My is not working because it was in airplane mode. I am wondering if anyone has had a similar experience and how long it took to get the phone returned. He is making do without it, but eventually needs a phone. I am wondering if anyone here has tips from a similar experience I can pass along to him.
