London LGW to USA one way fares
Norwegian prices their tickets as one way fares, even for round trip travel. This results in one way fares being lower priced when purchased through a European site for the flight to the USA. Google Flights automatically creates links to two different Norwegian Airlines websites when searching these fares to price the USA-UK flight in US Dollars and the UK to USA flight in British Pounds. The resulting fare is less than purchasing a round trip ticket from the USA site and also reduces the cost to upgrade the ticket to Low Fare+ for one checked bag, seat assignment and meal included.
