View the current offers here.Per this FlyerTalk thread, there are some lovely $300 one-way or $600-$700 round-trip deals right now from SFO and other Bay Area airports to Gotenburg, Sweden. Tickets must be purchased by February 23, and there is no advance purchase requirement (meaning you can fly to Europe tomorrow if you want!). Similar to last week’s LAX - Billund, Denmark fares, these flights can be purchased as one-way flights as well.I was able to find several routings for these flights through London (LHR), Helsinki (HEL) and even Madrid (MAD). I was also able to find flights throughout April and May, in the height of summer (with select dates), and even in the early Fall.The best way to quickly search for these available fares is to use the ITA Matrix calendar search, and play around with the cities and dates that interest you. I recommend choosing the option to see the calendar of lowest fares when searching.Here are a few of the deals I was able to find:From San Francisco via London $681 round-trip on British AirwaysSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
