I bought tickets with premier and flexible, I mean paid extra. After that, I changed my booking due to some change of planning. Seems to me everything was okay as there was no issues upon changing ticket. The same day, my plan was changed and cancelled my ticket, it was a big shock for me that they offer me $10 dollar refund, I call the customer, they are well trained for this kind of issues, realized I am not the only one in this scam. I am paid extra for to change any unknown things happen, but they are not only trustworthy but also fraud. They are doing there business wrong way, they are strong because they operating this fraud business from somewhere in the corner of world. So please book through airlines or registered agent not this kind of online fraudsters
