Official map
San Juan official terminal map — airport authority website
Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at SJU handles — which airlines fly from it, the gate range, and key amenities to know before you go.
A standalone building opened in June 2012 with its own dedicated ticketing, check-in, and security checkpoint — separate from the rest of the airport. Eight gates (A1–A8) serve JetBlue Airways, which bases its largest Caribbean operation here, plus Air Canada, Avelo, and Tradewind Aviation. Home to "The Lounge San Juan," a Global Lounge Network Priority Pass lounge.
Reopened in December 2014 after a $130 million renovation of the original Eastern Airlines terminal; now a 25-gate concourse (gates B2–B10) serving Delta, United, Southwest, Spirit, and Air Canada. Shares one consolidated security checkpoint with Terminals C and D. Dining includes La Carreta (Puerto Rican) and Chili's; the Escape Lounge sits near Gate B2.
Reopened in March 2016 after a $55 million renovation (originally built in 1996 as a Terminal B expansion); nine gates (C2–C10). Primary base for Frontier Airlines, also serving American, Avianca, Copa, and Iberia, plus JetBlue's international arrivals. Has the airport's higher-end retail and dining cluster and the Avianca/Global Lounge Network VIP lounge on the 3rd floor.
Reopened March 2023 with 8 gates (5 regional, 3 mainline-capacity), serving Cape Air, Caribbean Airlines, and InterCaribbean Airways, plus overflow operations for Delta, Frontier, Spirit, and United. The on-site San Juan Airport Hotel sits on the 2nd floor here. The former Terminal E remains closed pending future renovation.
No train or tram at SJU — every connection is on foot. Terminals B, C, and D are physically joined and share one consolidated security checkpoint, so once you're through security you can walk airside between all three (the two farthest gates are about 0.6 miles apart, roughly a 15-minute walk). Terminal A is a separate building with its own check-in counters and its own security checkpoint; moving between Terminal A and B/C/D means leaving the secure area and walking over landside, not an airside connector.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at SJU — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
Treat a Terminal A ↔ Terminals B/C/D connection like starting your airport visit over: Terminal A runs on a completely separate checkpoint, so you must exit security, walk to the other building, and re-clear screening. Build in real extra time — this is the single most common layout mistake at SJU, especially for JetBlue (Terminal A) passengers connecting to or from Delta, United, Southwest, Spirit, Frontier, American, or the regional carriers in B/C/D.
A few habits that prevent last-minute sprints:
Experienced travellers at SJU use a short checklist every time:

Your boarding pass shows the exact gate. Open your airline app about two hours before departure — gate assignments sometimes change after check-in closes. Look for departure boards throughout the terminal for real-time gate information.
