Perfect Trip  5
I was pleased that the entire trip went so smoothly. I was reluctant to try One Travel at first but now I would highly recommend One Travel as a safe bet. I could not have been more please and I'm certainly book with them again.

Wonderful flight  5
My friends recommended Iceland Air to us after honeymooning in Europe the summer of 2014. I had never heard of Iceland Air before. It was nice to fly from Anchorage to Iceland (6 h 45 min), take a 1.5 hour layover, then fly onto London (2 h 40 min). It was easy to book with One Travel. We will definitely book with One Travel again. Thank you for helping us create the perfect family vacation.
