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 might 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.Primera Air, the relatively new low-cost carrier, is offering $99 one-way flights on some of its transatlantic routes. As part of this sale, you can fly from Boston (BOS) to London (STN) for as little as $99 one-way, or $303 round-trip. We’re also seeing low fares from its other US gateways to both Paris (CDG) and Birmingham (BHX) — though you may have to pay just a bit more than $99 one-way.To search for these flights, head to Google Flights and enter your origin and destination. Then, use the calendar function to scroll through and find dates and prices that work for you. Finally, click through to book directly with the airline.Airline: Primera AirRoute: BOS/EWR to BHX/CDG/STNCost: $99+ one-way/$303+ round-trip in coachDates: April 2018; September - December 2018Pay 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 dates you can book:Boston (BOS) to London (STN) for $99 one-way ($309 round-trip):Newark (EWR) to Birmingham (BHX) for $99 one-way ($309 round-trip):Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
