If you want to fly from San Francisco to London in September, the non-stop Norse Atlantic flight is the cheapest option available on Google Flights.


For return flights, Google Flights shows the September 14 flight back to San Francisco as one where you need to book the tickets separately to get the lowest price.

Although Google Flights shows the round trip price between San Francisco and London as $485, the ticket actually costs $502 if you book the tickets directly on Norse Atlantic’s website. Sometimes Google Flights may show price discrepancies between the prices and the prices on the airlines’ websites due to the availability of third-party options.


On Norse Atlantic’s website, the price is $502 return for the airline’s light class; with this fare, passengers can only bring one personal item on board and change tickets by paying a fee. The fare from San Francisco to London is $184 and the return fare is $319.


Considering that Norse Atlantic’s economy light fare is pretty bare bones, you’ll have to pay extra if you plan to bring carry-on and checked bags. A carry-on bag costs $45 one way, and a standard checked bag costs $70.


Seat selection also costs extra. Standard seats cost anywhere from $20 to $35 extra, while seats with the most legroom cost $100. Preferred seats are $60.

These flights can fill up quickly and are likely to change soon, so buy these tickets while you can.
