Several online travel agencies are currently selling Oneworld business class tickets from Dublin to North America at roughly 50% off standard commercial rates. Because these fares undercut direct airline pricing by more than €1,000, we recommend waiting until an official e-ticket number has been issued before making non-refundable hotel or positioning travel plans.
Long-haul segments are operated by British Airways and American Airlines. A wide range of destinations across the USA are available, alongside Canadian gateways like Toronto and Vancouver.
Here are the lowest round-trip business class fares we identified from Dublin:
- Washington D.C. from €1,062
- New York from €1,071
- Las Vegas from €1,111
- Miami from €1,149
- Tampa from €1,175
- Boston from €1,206
- San Antonio from €1,248 (2 layovers)
- Vancouver from €1,347
- Seattle from €1,359

All itineraries route via London. Flights between Dublin and London Heathrow (LHR) are operated by British Airways (Club Europe) or Aer Lingus. From London, you connect to transatlantic flights operated by British Airways or American Airlines.
British Airways operates its modern Club Suite (with sliding privacy doors and direct aisle access) across most of its A350, Boeing 777, and refurbished 787 fleets. However, note that BA’s Airbus A380 (frequently deployed to Miami) still features its dated 2-4-2 Club World cabin; on routes with the A380, choosing American Airlines may provide a superior seat. Additionally, departures on American Airlines fly out of London Heathrow’s Terminal 3, granting access to superior oneworld partner lounges (such as Cathay Pacific and Qantas). Regardless of airline, all transatlantic flights feature fully lie-flat beds.
Search & Book
The exact duration of these discounted OTA fares is unpredictable. We found availability on sample dates from November 2026 through June 2027.
A minimum stay of a Saturday overnight stay is required, with a maximum stay of up to 12 months.
Searching for dates can be tricky because neither Google Flights nor the ITA Matrix display these heavily discounted OTA rates. Your best strategy is to test individual date pairs directly on Skyscanner or directly via Booking.com’s flight portal.

Note on frequent flyer credit: The exact mileage earned with British Airways Executive Club, Iberia Plus, or American Airlines AAdvantage will depend on which airline’s ticket stock (001 for American, 125 for BA) the OTA issues. Distance-based partner crediting rules apply if issued on partner ticket stock.
