Icelandic low-fare carrier Wow Air just stopped flying, stranding passengers on both sides of the Atlantic. The Washington Post has a story on what to do if you're stuck:
https://www.washingtonpost.com/lifestyle/travel/i-have-a-wow-air-ticket-what-happens-now/2019/03/28/2bda45f0-5182-11e9-8d28-f5149e5a2fda_story.html I'm sad about this, not because I ever had much intention of flying with them, but because when the transatlantic low-fare airlines like Laker Airways and People Express Airlines stop flying, the network carriers raise their prices.
RIP, Wow. Hope Norwegian stays in the air until the end of the summer.
