San Juan's airport is packed with people, so many of them very old or very young.
I have never seen so many dogs at the airport. It's clear that most of the passengers have a one-way ticket. They simply don't know when — or if — they'll be able to return. So many people outside the checkpoint were crying, waiting and watching until their loved ones disappeared into the terminal.
At the TSA checkpoint, an elderly woman in a wheelchair struggled to hold her dog, a dappled dachshund and the doppelgänger to my own dog, so I offered to help with the dog. The woman said, "I've never flown with her, and I can't find her leash."
