GOOGLE FLIGHTS

For returning flights, Google Flights lists the Sept. 14 flight back to San Francisco as one where you’d need to book the tickets separately to get the lowest possible fare.

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

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

NORSE ATLANTIC

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

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