If you need to change your itinerary and dont mind paying the super high extra charges Cheapoair is not the company you want to go with. They really suck with customer service or caring for the customers and even listening to customer concerns. I needed to leave Greece to Barcelona couple day early because of a family emergence and I called them I was put on hold or transfer and the call hung. They didnt bother to call me back. I called several times and I told them I am using a 20 euro calling card so to please rush and to book the earlies t flight back- just put me on a long wait and hung up. Then I tried to reach them online through Cheapoair's state of the art "chatroom" it took me 2 hours to get someone to respond back with a quote and couldnt even book anything. The person that I chatted with promised that someone will contact me back and no one did I waited 24hours. Than finally I emailed them with my concerns and asked them to change my flight date and again no response. So I ended up having to book my flight with a different company SO DISAPOINTED never using CHEAPOAIR to book any of my trips again. WORST SERVICE
