Aer Lingus has New York returns from £379, Toronto from £419 and Los Angeles from £446 in its North America sale. The fares connect via Dublin, but US Preclearance means you can clear American immigration before the Atlantic flight.
That gives this sale more life than a single cheap New York fare. The same page has London Heathrow to San Francisco from £445.76 return, plus regional departures including Manchester to New York from £423.32 and Toronto from £401.82. Book by 29 September for travel from 1 October to 19 March.
The lowest London examples are 2 to 8 December for New York, 30 October to 8 November for Toronto and 8 to 16 November for Los Angeles, checked on 8 September. Fares include taxes and charges, are sold as return trips and require a Saturday-night stay. All transatlantic flights connect in Dublin.
How to book
Open the Aer Lingus North America sale page, select your airport and compare dates before paying. Keep an eye on flight times if you want to use US Preclearance, as it is unavailable on evening Boston and New York JFK services until 24 October.

How Kate works
Kate checks the details that can change the value of a trip, including cabin-bag rules, airline fees, hotel location, seasonality, travel dates and booking conditions. She is especially interested in offers that look useful on the surface but need a proper reader-first check before they are worth recommending.
Editorial standards
Flight Tribe covers deals and travel advice for readers first. Affiliate links do not decide whether an offer is worth writing about.
