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 Platinum Card® from American Express, you’ll need to book directly with the airline or through the 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.Icelandair is offering crazy-cheap flights to London from across the US. Due to the high taxes/fees out of London, some of these base airline fares start at just $23. So, it really doesn’t get cheaper than this.Note that some of the cheapest options require an overnight in Iceland on the return leg. If you want to make it a two-in-one trip, you can stretch this layover into a multi-day stopover for no additional airfare. You’ll want to book these flights directly through the airline to take full advantage of the perks.Although its a low-cost carrier, Icelandair actually provides a decent in-flight experience. In addition to including a free carry-on bag for all economy passengers, Icelandair provides free in-flight entertainment via seatback screens, has USB power ports and even provides pillows:To book, head to Google Flights and input your departure city and London as your destination.
