Looking at an AA flight to SXM in the fall. Connection with terminal change in PHL. Connection time is shown as 1H 20M. Not the best connection choice but it would allow an additional day on the island. This connection is on the way TO SXM so customs and immigration are not an issue. Being a regional jet that I would be coming in on, I am assuming it would arrive at Terminal F as that was the arrival terminal today. Not sure what terminal the outbound flight to SXM departs from but today it was Terminal A.

Is a connection in PHL on a Saturday from Terminal F to Terminal A doable in 1H 20M or should I scrap that thought? Other option is Sunday travel and connect through CLT but a day less on the island.

Another reason I am considering this connection is price as the Saturday flight through CLT is more than a few $$ higher.

Thanks.
