Cheap flights from London to Austin

The shoulder weeks around late spring are where fares soften first, and May comes out as the cheapest month — warm in Texas, ahead of the full summer heat and ahead of school holidays in the UK and the US, when prices tend to climb. Expect the Christmas period and the American spring-break weeks to price higher, along with the summer months. The calendar on this page covers October through August, so slide your dates across those months before you settle; travelling midweek rather than at a weekend often trims the fare too.

British Airways is the name most travellers weigh first: a full-service carrier whose transatlantic fares normally include checked baggage, meals and drinks, so the quoted fare is close to the final one. American Airlines and United Airlines run a comparable full-service product, worth checking if you collect miles on the US side. Swiss, Austrian, Brussels Airlines and Iberia turn up mainly in one-stop itineraries, with a change somewhere in Europe before the crossing — often gentler on the budget, rarely on the clock. Air Transat works as a leisure carrier, so check what its fare includes before comparing, while Republic Airways flies regional equipment on shorter US sectors.

Sort out your entry paperwork for the United States before you fly — check whether your passport qualifies for an ESTA or needs a visa — so the only formality waiting at the airport is the immigration queue. You land at Bergstrom International, a short drive from downtown Austin, with taxis and rideshares outside the terminal and car-hire desks close by. Leave buffer time after the transatlantic crossing if someone is meeting you, and plan how you will get around: central Austin is walkable in patches, but the wider city is sized for cars, so many visitors rent one.

Country facts: Wikidata

• Check your passport and US entry authorisation — an ESTA or a visa — well before booking, since approval is not instant.
• Confirm which of the five London airports your ticket leaves from — City, Gatwick, Heathrow, Luton and Stansted sit far apart.
• If your trip uses two separate tickets, check the connection leaves enough slack for one delay not to sink the other.
• On leisure-carrier fares, check whether checked baggage and meals are included, or the total will not match the quote.
• Compare dates across the calendar from October to August, with May usually the cheapest.
• Book early for Christmas and school-holiday weeks, when fares on this route climb.
