Norwegian Airlines via ShermansTravel offers Norwegian Airlines 1-Way Flights to Europe from select cities in the U.S. for as low as $125.20. (On the ShermansTravel landing page, click on "" in the main paragraph to see this offer.) That's tied with our mention from two weeks ago and the lowest price we could find for select routes today by at least $32. This price is based on departure on March 27 from Boston, MA, (BOS) with arrival in London, England, (LGW). Note that this airline is a "non-bundle" airline, so seat reservation and luggage costs are additional. Book this travel deal by March 31.
