Delta A330neo Upgauges Boston–Dublin Route
Delta is swapping its Boeing 767-300ER for an Airbus A330-900neo on the Boston–Dublin run starting October 26, 2025, boosting capacity by about 25%.
Delta Air Lines (DL / ICAO: DAL) will upgauge its Boston Logan (BOS) to Dublin (DUB) service — flight DAL154/5 — from October 26, 2025, replacing a 225-seat Boeing 767-300ER with a 281-seat Airbus A330-900neo. The change shifts the route to four weekly rotations and reflects Delta’s push to match strong transatlantic demand with newer, higher-capacity aircraft.
The A330-900neo brings three-class cabins and modern passenger amenities compared with the older 767-300ER. For travellers between Boston and Ireland, that typically means more seat availability, refreshed inflight systems and a quieter cabin. Delta markets the move as both a capacity and comfort upgrade on a key US–Ireland link.
Delta A330neo: what changes for passengers
Operationally, DAL154/5 will keep its schedule pattern but will carry roughly 56 more seats per flight — about a 25% uplift in single-rotation capacity. The A330-900neo is also more fuel-efficient than the 767-300ER it replaces, which fits Delta’s fleet modernization goals and helps the airline manage long-haul economics on competitive transatlantic lanes.
- Key facts: Delta A330neo replaces B767-300ER on DAL154/5 from October 26, 2025; four weekly flights; 225 → 281 seats; BOS ↔ DUB.
From a route strategy angle, the upgauge gives Delta (DL/DAL) more flexibility to meet seasonal peaks and growing demand for nonstop travel between New England and Ireland. While ticket prices will still vary by demand, more seats usually mean better availability for award travel and last-minute bookings.
Frequent flyers should watch seat maps and fare buckets after the swap; premium cabin counts will change as carriers rebalance inventory on larger airframes. For airport partners at Boston Logan and Dublin Airport, the move is a modest capacity increase without adding frequencies — a simple aircraft change rather than a schedule expansion.
