Cheap flights from London to San Juan

February is the cheapest month on this route, so aim for it if your dates can move. The price calendar covers every month from September through August, which lets you see how the rest of the year sits before you commit. Winter departures from London are busy and sell out early, while late spring and early autumn usually land somewhere in the middle. Midweek flights tend to cost less than weekend ones, and connections through European hubs are easier to line up early in the week.

Nothing flies this route non-stop, so every itinerary is a connection, usually through a European or North American hub. KLM Royal Dutch Airlines, TAP Portugal, Swiss, Brussels Airlines, Lufthansa City Airlines and Air Dolomiti are full-service, and their fares normally include a checked bag, food on the long leg and a connection the airline rebooks if a flight is delayed. Easyjet and Wizz Air Malta are low-cost: you pay for the seat and a small cabin bag, then add luggage and seat choice. Royal Air Maroc and Air Canada Rouge fly longer routings that can price lower. Check whether both legs sit on one ticket.

You land at Luis Munoz Marin, the gateway airport on the edge of San Juan and the only one you will use on this route. It sits close to the old town and the beach districts, a short drive rather than a long transfer. Taxis and ride-share pick-ups work from the arrivals curb, and shared shuttles run to the hotel strips. If you arrive on a late connection from Europe, leave some slack in your plans for immigration and for getting into town, and keep your first night's check-in time flexible.

Country facts: Wikidata

• Check which London airport you fly from — Heathrow, Gatwick, Luton, Stansted or London City — since switching between them is slow.
• Check whether your Easyjet or Wizz Air Malta fare includes a checked bag, or plan to add one.
• Make sure both legs sit on one ticket, so a missed connection is covered.
• Look up the entry rules for Puerto Rico before booking, as they differ from a European trip.
• Compare February with your own dates in the price calendar; the gap between months is wide.
• Leave room in your plans if you land late and still need ground transport into San Juan.
