Delta Air Lines launched a surprise 72-hour flash sale today offering round-trip flights to multiple European destinations starting at $399 in main cabin. The sale covers travel dates from September through November 2026, traditionally the shoulder season when crowds thin and weather remains pleasant across much of the continent.
Standout deals include Atlanta to Barcelona for $399, New York JFK to Rome for $429, Minneapolis to Paris for $449, and Detroit to Amsterdam for $419. Business class fares are also discounted, with Delta One suites to London available from $2,200 round-trip, roughly 40% below typical pricing for the premium cabin product.
The sale is available to all travelers but SkyMiles members receive an additional 2,000 bonus miles per booking when purchasing through the Delta app. Travel must be booked by April 17 at 11:59 PM Eastern. Delta's sale appears to be a response to similar promotions from American Airlines and United in recent weeks as carriers compete for fall travel bookings. Fare experts recommend using Google Flights to compare dates and airports for the best prices within the sale window.
