Have you heard of wegolo.com? I found them through Kayak. They offer better rates on certain “low cost” flights by splitting return tickets into two one way and get interesting results. But the only thing I can find about them is: Wegolo is a trade name of Beins Travel Group, with its main office located at Arendshof 85, NL-4901 LK Oosterhout, in the Netherlands (registered in the Netherlands under Registration Number 20042808).
This is the same address that cheaptickets.nl operates from. It is a proper travel agents and I’m guessing that Beims Travel, Wegolo and cheap tickets.nl are all the same owner. I’ve used cheaptickets in the past for my kids and had no problems.
