What Does Business Class from Seattle to Dublin Cost?
Business class from Seattle to Dublin is one of the most underbooked transatlantic corridors in North America, and CEOFLIGHTS clients regularly secure round-trip fares between $2,400 and $6,800 — often 40 to 60 percent below what the same seats list for on public booking sites. Seattle-Tacoma International Airport (SEA) connects to Dublin Airport (DUB) across a 9.5-hour flight operated by Delta Air Lines, Aer Lingus, and American Airlines, making this a genuinely competitive route with multiple premium cabin options throughout the year.
How much does business class from Seattle to Dublin actually cost? The honest answer depends heavily on when you book and who books it for you. Published fares on this corridor can spike above $6,800 round-trip during peak summer travel, but travelers who work with a CEOFLIGHTS Personal Travel Manager consistently access private and consolidator fares that bring that same seat down to the $2,400 to $3,800 range. These are not publicly listed rates — they exist in wholesale channels that individual travelers simply cannot reach on their own.
When Is the Cheapest Time to Fly Business Class to Dublin?
The best months to fly business class from Seattle to Dublin on a value basis are January, February, March, October, and November. During these shoulder and off-peak periods, transatlantic demand drops significantly, and airlines release a higher volume of discounted premium cabin inventory. A traveler flying in February versus July on the same carrier can realistically see a price difference of $1,500 or more on a round-trip business class ticket — a gap large enough to justify planning your Dublin trip around the calendar.
Aer Lingus operates nonstop service between Seattle-Tacoma International (SEA) and Dublin Airport (DUB), making it the most direct option on this route and a strong choice for travelers prioritizing efficiency.
