So sorry for responding late. Life got very busy once we returned home. So….Our flight from SXM to Miami went smooth but came in about 15 minutes late. The signage to Immigration was easy to follow but we never realized how far we’d have to walk to get there. We came in at the end of concourse E. The sign listing flights and luggage location were harder to follow as it is an electronic sign that kept updating the myriads of flights arriving. We finally figured it out, grabbed our luggage and proceeded to drop off our bags before going through TSA. We then realized that I had not checked our luggage all the way through to PHL when we were in SXM. We usually fly direct PHL to SXM and had never flow into MIA. We told one of the attendants our lot and she kindly handed us an orange ticket, opened the rope barrier, and let us through to an area just ahead for us, and others, who needed to check in luggage. The line going into TSA was so crowded with people we wondered at that moment if we were going to make our flight if we had to go to the back of that line after checking in luggage. We waited a bit in a line of about 8 people and checked in the luggage. The attendant asked what time our flight left before taking our luggage. I could see by the look on her face she was calculating whether we had time, nodded and checked in our bags. The sweet spot was once we checked in our bags they opened a space up ahead of the lines for us to go through TSA. We now had to walk, or rather speed walk, all the way back to the same concourse as we had arrived. Both of us had to hit the head before we boarded, and we arrived at the gate just as they were calling our group. It was all very exhausting and stressful but we made it. We logged 9,000 + steps so I thought it all turned lemons into lemon aid in the exercise dept. Lesson learned about checking luggage all the way through to your destination. I’m not sure I ever want to do a connecting MIA again, but you can’t always get direct…so who knows. On the flight to SXM we stayed overnight in Miami as connecting flights to SXM didn’t allow much time at all.
