About flights to Puerto Rico
Overview
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.
Best time to fly to Puerto Rico
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.
Main gateway cities & airports
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.
Airlines and routes
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.
Popular places to visit in Puerto Rico
- Old San Juan: cobbled streets, colourful facades and the El Morro fortress
- El Yunque National Forest: the only tropical rainforest in the US park system
- Culebra & Vieques: stunning offshore islands and Flamenco Beach
- Bioluminescent bays: glowing waters best seen by night kayak

Top tips for finding cheap flights to Puerto Rico
- Book a few months ahead for the December–April peak.
- Compare US and European connections — routings can vary in price.
- Travel in the shoulder months (May or November) for lower fares.
- Be flexible with dates — midweek departures are often cheaper.
Travel essentials
- Entry: Puerto Rico is a US territory, so UK travellers must obtain a US ESTA before travelling, as for the mainland USA
- Health: no special vaccinations are required for most trips
- Currency: the US dollar (USD)
Baggage & hand-luggage allowance for flights to Puerto Rico
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 |
Indicative only. Allowances vary by airline, route and fare — always check your airline's baggage policy.
Packing & baggage tips
- Full-service carriers (e.g. British Airways, Turkish Airlines, KLM) usually include a checked bag on long-haul economy fares; basic/low-cost fares often don't.
- Cabin (hand) bag size is commonly around 56 × 45 × 25 cm — confirm your airline's limit before you pack.
- Liquids in hand luggage must be in containers of 100 ml or less, inside one clear resealable bag.
- Weigh your bags at home — airport excess-baggage fees are far higher than pre-booked allowances.
- Extra or heavier bags are almost always cheaper added online in advance than at the airport.
