Just in case somebody booked a flight with them, start re-booking the flights while there are some seats available.
I had one flight booked and paid with them and fortunately a friend called me about the bankruptcy in the morning, so I was able to act right away, and get my refund and re-book the trip with another airline. Both, WowAir and the 747 MAX problems will affect quite a few travellers.
Icelandic budget airline WOW Air abruptly closed up shop on Thursday, stranding thousands of passengers including Canadians across Europe and North America.
In a statement on its website, the airline said it has ceased operations, and as a result "all WOW Air flights have been cancelled."
