About this route
San Juan (SJU) to Miami (MIA) is one of the busiest air routes in its market (Canada, Mexico & Caribbean). It links Luis Munoz Marin International Airport in Puerto Rico with Miami International Airport in United States. The great-circle distance is about 908 nautical miles (1,045 statute miles), so expect roughly 2.5 hours in the air nonstop.
Every night we ask our fare provider for the cheapest one-way economy fare other travellers recently found on this route and record it, with the airline and the seller it was found with. A fare is flagged as a deal when it falls at least 30% below the route's 90-day typical price. Prices are a research starting point, not live availability — the booking links open the itinerary so you can confirm what's on sale right now.
Fares are approximate, from public sources, and can be stale — always verify before booking.
