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.Iceland is one of my favorite places in the world because of its jaw-dropping natural beauty, and everyone should considering adding it to their bucket list.https://www.instagram.com/p/BV3Xk37nRFB/The Icelandic ultra-low-cost carrier Wow Air made getting to the country incredibly easy due to its dirt-cheap fares. However its ridiculously low prices were one of the many reasons the carrier has cut most of its US routes over the last year. Wow is reportedly being rescued by an investment from Bill Franke who owns US budget airline Frontier.The carrier is still operating four routes between the US and Iceland, and its selling super cheap tickets to the country, with prices starting from $145 round-trip. That’s cheaper than most short domestic hops! Just note that this only comes with a small personal item — you’ll have to pay extra for a large carry-on, checked bag, seat selection, etc. Still, there’s plenty of room for savings with prices like this.Since Wow is still in a financial grey area, it’s important to know that if you do book these tickets, the airline may not be around in a few months’ time. That means book refundable accommodations and pay with a card that has trip cancellation insurance. If you’re more risk-averse, Icelandair has round-trip prices starting from $314.As we’ve warned before, if you do nab one of these flights, make sure to put the purchase on a credit card with travel insurance — cards like the Chase Sapphire Reserve or Citi Prestige offer some of the best-in-class protections in case the airline goes belly up. Also, the European Union’s 261 rule requires airlines to get you to your final destination or refund you the cost of your ticket.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
