Cheap flights from London to San Salvador

February is the cheapest month for this route, and the months from September through April all carry published fares, so the price calendar is worth a look before you commit. The dry season in El Salvador runs roughly from November to April, which is also when the northern winter pushes London fares up around Christmas and New Year. Flying out on a Tuesday or Wednesday and returning midweek usually costs less than a weekend departure. School holidays in the United Kingdom lift prices; if your dates are flexible, aim for the weeks between the holiday peaks.

No airline flies this route non-stop, so every ticket pairs a long-haul leg with a connection. Iberia, KLM Royal Dutch Airlines, Lufthansa, Swiss, TAP Portugal, Virgin Atlantic and AeroMéxico are full-service carriers, so what comes with your ticket depends on the fare family you choose. Iberia Express and KLM Cityhopper are the short-haul arms of Iberia and KLM, and they often operate the first leg out of London. Air Europa also sells connections here. If you book a low-cost leg separately, baggage and seat fees add up fast.

Comalapa International is the airport you land at, and it sits outside San Salvador rather than inside the city, so the last stretch of the journey is a road transfer. Taxis, shared shuttles and pre-booked private transfers are the usual ways into town, and it is worth arranging one before you land if you arrive after dark. Immigration and customs can take a while when several long-haul flights come in close together, so build some slack into your first evening.

• Confirm which London airport you fly from, since London City, Gatwick, Heathrow, Luton and Stansted are not interchangeable.
• Check whether checked baggage is included on both legs, as they may be sold by different carriers.
• If you book the connection on separate tickets, leave enough time to clear immigration and re-check your bag.
• Check passport validity and any entry requirements for El Salvador well before departure.
• Compare fares across the winter months, since February is the cheapest month on this route.
