We were re-assigned to a later flight on a different airline at 8pm (adding three more hours to our two hour layover), which, when we arrived at the gate, we learned had been cancelled, subsequently bumping us on to an even later flight at 9:45pm. This was very bad news to us considering we had three small children who had been traveling for over twelve hours and were in dire need of sleep. We also had three exhausted adults who hadn't had a decent meal in hours and were in dire need of a team of chiropractors (baby wearing is great, but after a full day of it, it can get...tiring). It didn't end there either, apparently due to all the shuffling of passengers from two earlier cancelled flights, the plane - we were told - no longer had a seat for my mom. It looked like Grandma would have to stay back in San Juan and be on the first flight out at 8am. Not the end of the world, of course, but rather annoying considering if we had been on our original flight the three of us would have been sipping painkillers while the kids slumbered in their beds.
