This is a total scam. You put a flight in your cart at one price and then pay and the fee doubles. And the response from "support" is just some canned "oh no, that's not the experience we want for you" but it keeps happening. They blame it in the airlines but that NEVER happens with any other travel site. Is their app adding on fees. They refuse to fix it or help in any way. Worst service. Horrid experience.
