AD PLACEMENT — CONTEXTUAL
If your connection spans Terminal A and Terminal B/C, budget extra time for the shuttle and a second security screening.
JetBlue's Caribbean 'bank' of departures clusters in the afternoon, so gate areas in Terminal B/C get crowded from roughly 3-6pm.
Flights arriving from foreign countries (like the Dominican Republic or Aruba) require CBP processing at SJU, even if your final leg is domestic within the US.
Terminal A is smaller and has fewer food options, so grab food in B/C if you have time before a same-terminal connection.
PreCheck lanes exist but are limited, so don't assume the shortest line during peak morning or afternoon banks.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminals B and C are linked airside by a short walkway, so connections between JetBlue and Spirit gates typically involve no re-screening. Moving to or from Terminal A requires exiting security, a landside shuttle bus or walk of several minutes, and a full re-screening on the other side.
