Follow The Points Guy on Facebook and Twitter, and subscribe to text message alerts from our deals feed, @tpg_alerts.Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency, such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using the American Express Platinum Card, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.Update 6/1/2017 12:26pm: It looks like WOW’s $55 one-way tickets are a hit (no surprise there) — the carrier’s booking engine is down for the time being.WOW is currently offering $55 one-way fares from several US cities including Miami (MIA), San Francisco (SFO) and Los Angeles (LAX) to Europe. This deal is only available for flights in June and on select dates. They’re selling out fast, so if you’re hoping to get across the Atlantic for a bargain-basement price, head over to WOW’s site right now. If you’re feeling lucky (and know a little bit of German, to boot), play around on WOW’s German website to find low one-way fares for your return.Airlines: WOWRoutes: SFO to AMS/CPH/DUB/LGW/SXF, MIA to BRS/BRU/CPH/DUB/DUS/EDI/FRA/ORK, LAX to AMS/CPH/DUB/LGW/SXFCost: $55+ one way economyDates: June 11 - June 28Booking Link: WOW or ExpediaPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare) or Chase Sapphire Preferred (2x on travel)Here are a few examples of what you can book:Miami (MIA) to Brussels (BRU) for $55 one-way:San Francisco (SFO) to Amsterdam (AMS) for $55 one-way:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
