El Salvador is Central America's smallest country and one of its most rewarding, packing Pacific surf beaches, coffee-covered volcanoes, crater lakes and Maya ruins into a space you can cross in a few hours. There are no direct flights from the UK, but its compact size means the highlights come quickly once you land, whether you visit on its own or as part of a wider Central America tour.
The dry season, roughly November to April, brings the most reliable sunshine, with coastal temperatures near 30°C and fresher air in the highlands around San Salvador. From May to October the green season delivers lush scenery and short afternoon downpours rather than all-day rain. Surf is good year-round, with the biggest Pacific swells from March to October. Check the When to book chart above for how fares move around UK half-term and Christmas.
Almost all international flights arrive at San Salvador International Airport (SAL), also called Monseñor Óscar Arnulfo Romero International, about 40 minutes south-east of the capital and 30 minutes from the La Libertad surf coast. It is modern, quick to transit and the main regional hub for Avianca. A small airport near San Miguel sees only limited traffic, so plan on SAL as your gateway.
No airline flies non-stop between the UK and El Salvador, so every routing involves a connection. A popular choice is London to Madrid with British Airways or Iberia, then Iberia's direct flight on to San Salvador. You can also connect through a US hub such as Houston, Miami or Atlanta with United, American or Delta – a US ESTA is needed even to change planes – or via Mexico City or Panama City, often with Avianca on the final leg. From Manchester you will usually route through Madrid, Amsterdam or a US gateway. Total journey time from London is typically 16–20 hours.
UK passport holders need no visa for tourism. On arrival you buy a tourist card (around US$12) allowing stays of up to 90 days across the CA-4 area of El Salvador, Guatemala, Honduras and Nicaragua; carry a passport valid for at least six months. The US dollar is the everyday currency, so cash is simple and cards work in cities. Check the When to book chart above, set a fare alert, and read current FCDO advice before booking.
Your allowance to El Salvador depends on the airline and the fare you book. The table below shows typical long-haul allowances so you know roughly what to expect — always confirm the exact limits with your airline before you fly.
| Fare type | Hand baggage | Checked baggage |
|---|---|---|
| Basic / Light economy | 1 small under-seat bag | Usually none — add for a fee |
| Standard economy | 1 cabin bag + 1 personal item | Typically 1 × 23 kg |
| Premium economy | 1–2 cabin bags + personal item | Typically 2 × 23 kg |
| Business / First | 2 cabin bags + personal item | Typically 2 × 32 kg |
