All good questions that I have no answers for. I would "guess" it is instructions from SXM ahead of time to let them know they will not get clearance to land and will have to meet the schedule SXM sets. Just speculation on my part. There is usually close to an hour of "fluff" built into the SXM schedules but you get delayed more than that or have a very tight connection to start with and you are toast with regard to getting home. The airline will be as responsible for as little as they can be.
Looking at the PJIA arrival schedule for today, it looks even heavier than yesterday. At least 10 big ones within a 3-hour window. Nothing new on the PJIA site or facebook page.
Below is what TTOL member JeanneB posted yesterday.
"I’m on the plane in CLT now. We “departed” on time, however, after we pushed back the pilot announced that we were going to be sitting here (on the tarmac) due to the “flow” in SXM for an hour and 10 minutes…."
BTW, has anyone seen or heard from Brian Mingo of late?
