Boston Logan International Airport diverted multiple flights for fuel and asked carriers to load extra fuel on inbound aircraft after weekend nor'easter storm shut off barge deliveries to the airport, the Massachusetts Port Authority (Massport) confirmed.

What happened at BOS

The fuel constraint followed a storm that swept the Boston region from Friday through Monday. Over 500 flights were cancelled at Logan during that window, according to FlightAware data. By Thursday evening, cancellations had dropped to eight across the previous 24 hours, suggesting the disruption had largely cleared.

The trigger was logistical. A Massport spokesperson told the Boston Herald that fuel ships could not make their scheduled runs up to Boston until the weather system passed. The airport held enough fuel to operate through the weekend, but the on-airport fueling consortium asked airlines in recent days to bring extra fuel aboard to "lighten the fueling load here."

How airlines responded

Delta Air Lines confirmed it was operating inbound aircraft to Boston with fuel allocated for the next scheduled flight out — a practice carriers call tankering — and was transporting additional fuel via tanker trucks to supplement reserves where feasible. "Delta remains in close contact with Massport and other aviation stakeholders at BOS and will continue to monitor conditions closely and provide updates as needed," the carrier said in a statement.

Delta did not disclose how many flights were affected. A Massport spokesperson deferred to airlines on how they "chose to respond to" the request.

Diversions and the customer experience

The operational pressure surfaced in the cabin. On a Wednesday Delta flight from Boston to Orlando that routed through Washington Dulles for a fuel stop, the pilot told passengers before departure: "Apparently just a shortage of fuel at the Boston airport."

Massport said an initial fuel shipment arrived at Logan after the storm on Tuesday, with a second on Wednesday. The return of barge deliveries, combined with tanker-truck top-ups and tankered inbound lifts, restored normal fueling posture by midweek.

What this exposes

• Single-mode supply risk. Logan receives jet fuel primarily by marine barge through Boston Harbor. A multi-day coastal storm halted that supply line, exposing the airport's dependence on a single delivery channel rather than pipeline or rail redundancy.
• Network ripple effects. Diversions to Dulles and other alternates cost airlines block time, fuel burn and crew-day disruption, while cancelled flights over the weekend cut capacity by more than 500 sectors in a four-day window.
• Carrier-side mitigation. Tankering increases trip fuel and burns, raising per-sector cost; tanker-truck deliveries are a stopgap, not a substitute for normal throughput.

What's next

Massport and the fueling consortium will need to assess whether seasonal fuel-reserve policies and barge scheduling absorbed the shock adequately, or whether backup supply arrangements — additional truck capacity, refined-product pre-positioning, or pipeline linkage — merit investment before the next severe-weather event hits the Northeast coast.
