Overview
San Antonio blends Texan hospitality with deep Spanish colonial roots, best known for the Alamo and the lively River Walk that winds through the city centre. It's a warmer, slower-paced alternative to Texas's bigger cities, and a great pick for UK travellers after history, good food and genuine Southern charm rather than a typical big-city break. There are no non-stop flights to San Antonio from the UK, so most journeys route through a major US hub before a short onward hop to San Antonio International Airport (SAT).
Best time to fly to San Antonio
Spring (March to May) and autumn (September to November) are the sweet spot, with warm days, low humidity and events like Fiesta San Antonio in April. Summers are hot and sticky, often into the mid-30s°C, while winters are mild with only the occasional cold snap.

Airlines and routes
Getting to San Antonio from the UK always involves a connection. American Airlines typically routes travellers via its Dallas/Fort Worth hub, with a quick onward flight of around an hour to SAT. United Airlines connects via Houston or Chicago, and Delta via Atlanta, all with a UK departure first. British Airways passengers usually connect onto a partner airline at a US gateway. Total journey time from London is typically 12 to 15 hours including the layover, with the transatlantic leg alone around 9 to 10 hours.
Things to do in San Antonio
San Antonio rewards a few unhurried days of exploring on foot and by river taxi.
- The Alamo: The iconic 18th-century mission and site of the 1836 battle, now a free-to-enter historic shrine in the heart of downtown.

At San Antonio International Airport (SAT)
SAT sits around 8 miles (13km) north of downtown, roughly a 15 to 20-minute drive depending on traffic. Taxis and rideshare services are readily available outside arrivals, and VIA Metropolitan Transit buses run into the city centre for a low-cost option. Most major car hire firms operate from the airport, which is worth considering if you plan to visit the outlying missions or day-trip further afield.
Top tips for finding cheap flights to San Antonio

- Flying midweek, particularly Tuesday or Wednesday, is usually cheaper than weekend departures.
- Stay flexible with dates where possible, as shifting by even a day or two either side can unlock a noticeably better fare.

Travel essentials
UK passport holders need a valid ESTA (Electronic System for Travel Authorization) before travelling under the Visa Waiver Program, applied for online in advance rather than a full visa. The currency is the US Dollar, and card payments are accepted almost everywhere. No specific vaccinations are required for entry, though comprehensive travel insurance is strongly recommended, and it's worth checking your passport has at least six months' validity before departure.
