British Airways launched a 25 percent discount on all transatlantic economy fares on 20 June 2026. The promotion applies to travel between 1 and 31 August with returns from GBP 299 London-New York. Business class seats start at GBP 1,299 on the same routes.
Twelve US destinations participate including Boston, Chicago, Miami and Los Angeles. Upgrades using Avios points receive a 30 percent bonus during the sale period. Corporate contracts remain excluded from the discount.
Jet fuel prices dropped 18 percent year-on-year enabling the carrier to pass savings to passengers. August typically sees softer demand after school holidays end in Europe. Competitors Delta and United have not yet matched the pricing.
What this means for you
Book by 30 June for August departures to lock in the lowest fares. Compare flexible ticket options if your plans may shift due to summer weather. Add travel insurance covering flight changes at the time of booking.
Consider mid-week flights for additional savings of up to GBP 50 each way. Families should verify child discounts remain available on top of the sale price.
Similar promotions often appear in September so monitor airline newsletters. Book directly with British Airways to ensure easy changes if schedules alter.
