Funny story- A few years ago, my wife, son, daughter and I were sitting in the departure terminal in Philly waiting to board when my 20-something son informed us that his passport had expired. He was under 16 when he got his first one so it was only good for 5 years and the rest of ours were good for 10 years so we didn't pick up on it until it was a little too late. We decided to board the plane anyway and hope for the best. When we got to immigration, the agent flipped through the pages 3 times before looking up and telling us that the passport had expired. She explained that there was a 6 month grace period but that had also come and gone. I asked if that would be a problem. Having been to Jamaica a few times, I was hoping for the traditional answer to all questions asked of a Jamaican, "no problem, mon" but that didn't quite happen. We were detained for about 2 hours while they waited for the airline to send them a letter saying that they would take responsibility and agree to fly him back out of there at the end of the trip. It took about 5 Red Stripes to get my heart rate down.....
