Norwegian Air has announced plans to discontinue some flights between North America and Ireland in September. The airline is putting blame for the cuts on the extended grounding of the Boeing 737 Max. But it is also trying to focus on profitability over expansion. Three routes will be cut, effective September 15th of this year:

• Providence, RI to Dublin: Four weekly flights
• Newburgh, NY to Dublin: Daily flights
• Hamilton, Ontario to Dublin: Three weekly flights

Customers booked on affected flights have the option of either being rerouted onto other Norwegian flights or a full refund. Customers from the U.S. can travel to Dublin via Copenhagen, Oslo and Stockholm.

This will not affect the airline’s other long-haul services, operated by its Boeing 787 Dreamliner fleet. Norwegian currently operates 46 routes from the U.S. to Europe this summer season, more than any other European airline.
