Overview
Charleston is the South Carolina coast at its most graceful — cobbled lanes, pastel townhouses, a palm-lined waterfront and a food scene that punches well above the city's size. For UK travellers it works as a standalone break or as part of a wider tour of the American South alongside Savannah or the Carolina beaches. Here's how to reach Charleston from the UK, when to go and how to keep your flight costs down.
Best time to fly to Charleston
Spring (March to May) is the sweet spot: gardens in full bloom, warm days of around 20–26°C and the celebrated Spoleto Festival USA in late May. Autumn (September to November) brings similar comfortable weather with thinner crowds, though early autumn falls within the Atlantic hurricane season, so keep an eye on forecasts. Summers are hot and humid with frequent afternoon storms; winters are mild but quiet. Fares track demand closely, so check the When to book chart above to see how prices move through the year.
Airlines and routes
British Airways has operated a seasonal non-stop service between London Heathrow and Charleston, typically in the warmer months only, with a flight time of around 9 hours outbound and a little under 8 hours home. When the direct flight isn't running, most travellers connect through a US hub — American Airlines via Charlotte, Philadelphia or Miami, Delta via Atlanta or New York JFK, and United via Newark or Washington Dulles. Allowing for the layover, expect a total journey of 12 to 15 hours from London, and a little more from Manchester, Edinburgh or other UK airports routed via a hub.
Things to do in Charleston
The historic peninsula is compact and made for walking. Highlights include:
- The Battery and White Point Garden: a breezy waterfront promenade lined with grand antebellum mansions and old cannon.
- Rainbow Row: the postcard stretch of pastel-painted Georgian houses on East Bay Street.
- Fort Sumter: reached by harbour ferry, the sea fort where the American Civil War began in 1861.
- Charleston City Market: a covered market dating to the early 1800s, known for its sweetgrass basket weavers.
- The Ashley River plantations: Magnolia, Middleton Place and Boone Hall, with historic gardens and frank accounts of enslaved life.
At Charleston International Airport (CHS)
Charleston International sits in North Charleston, about 12 miles (19 km) north-west of the historic centre — a drive of roughly 20 to 30 minutes. Taxis and ride-hailing apps such as Uber and Lyft wait outside arrivals, and all the major car hire firms have desks in the terminal. CARTA public buses also serve the airport, though a taxi or private transfer is simpler with luggage after a long flight.
Top tips for finding cheap flights to Charleston
- Book roughly two to five months ahead for the best choice of fares; last-minute transatlantic seats are rarely a bargain.
- Fly midweek and steer clear of UK school holidays and the spring festival peak — the price charts on this page highlight the cheaper dates.
- Keep your dates flexible: shifting by a day or two, or travelling in the shoulder season, can cut the cost noticeably.
- Compare a connecting itinerary against the seasonal direct flight — one stop through a US hub is often cheaper for only a few extra hours.
Travel essentials
UK passport holders don't need a visa for tourism but must hold an approved ESTA under the US Visa Waiver Programme before travelling; apply online well ahead and expect a small fee payable in US dollars (roughly £17). Your passport should be valid for the length of your stay. The currency is the US dollar; cards are accepted almost everywhere, but a little cash is handy for tips. No special vaccinations are required, though comprehensive travel insurance with strong medical cover is essential, as US healthcare is expensive.
