Puerto Rico is a sun-soaked Caribbean island and US territory, pairing Spanish colonial history with palm-fringed beaches, rainforest and lively music. The historic capital San Juan is the main gateway, welcoming UK travellers seeking culture, warmth and easy island exploring.
The island is warm all year. The drier, most pleasant months run from December to April, the peak season, while summer is hotter and more humid, with a hurricane risk between June and November. Fares climb over Christmas and UK school holidays, so the price charts on this page show the cheapest dates for your route.
The main gateway is Luis Muñoz Marín International Airport (SJU) in San Juan, the island's principal hub. Smaller airports such as Rafael Hernández (BQN) at Aguadilla and Ponce (PSE) serve other regions.
There are no direct flights from the UK, so journeys involve one stop, usually through a US or European hub. American Airlines and United connect via US cities such as Miami, New York or Newark, while British Airways, Virgin Atlantic and Iberia (via Madrid) offer one-stop options from London. Total journey times are typically around 12–16 hours depending on the routing.
Your allowance to Puerto Rico 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 |
