The airline has put 360,000 seats on sale for next summer season with the cheapest seats available in economy class on the Boston route.
One-way flights to New York, Fort Lauderdale-Miami and Orlando lead in at £179 while West Coast airports Oakland-San Francisco and Los Angeles lead in at £199.
Thomas Ramdahl, chief commercial officer at Norwegian, said: “We’re releasing sizzling fares for next year’s summer programme as low-cost long-haul travel continues to take-off.
“With more state-of-the art 787 Dreamliners joining our fleet, UK passengers have more options to travel in fresh aircraft without breaking the bank.
“As we continue our UK expansion, consumers can expect to see more of Norwegian as we’re making it easier to travel in comfort with affordable fares to the top U.S. destinations.”
