Smart travel tips for departures from San Juan

• Plan ground transport with buffer time; AMA buses T5 and D53 are budget friendly but can take about one hour to Old San Juan and run roughly every 30 minutes, so allow extra time if traveling at rush hour, and consider a taxi or ride share if you have heavy bags.
• Know your terminal early; Terminals A, B, C, and D serve different carriers. Check your confirmation and follow airport signs to avoid backtracking, then arrive two hours before domestic flights and three hours before international.
• Use self transfer to expand options; if a nonstop is pricey or sold out, combine separate tickets on Kiwi.com to reach more cities, and add the Kiwi.com Guarantee for protection if carrier changes impact your trip.
• Track prices automatically; Set a Price Alert on your route, watch for drops, and book when the number fits your budget. This is especially handy for last minute flights from San Juan to major hubs.
• Keep everything in one place; Turn on automatic check in with the Guarantee, then store boarding passes and notifications in the Kiwi.com App for a calmer airport day.
