I had some passengers offload themselves after we had to return to SJU, following a noise reported by one of the girls in the back. It turned out to be nothing after the mechanics looked at it for about an hour (none of the other crewmembers heard the noise, but better safe than sorry) I explained to our shortly to become ex-fellow passengers exactly what had been done and I was happy with the result and that no more seats would be available for six more days as it was over Christmas time, but the final choice was theirs. Six days later I did the same trip, and I did see some familiar faces.
