Worst travel agency ever.... I am flying frequently between europe and north america since 20years. I never had any major issue using the plane company website everytime. last time I had to take a flight in a hurry, without knowing precisly the date of my return. I used opodo and their Flex option to be able to change my return easily. Turns out the flex option is working only until 24h before the departure of the first flight. Meaning you can't change your return after you took the first flight. First time I got screwed like that. I won't go for Opodo again and will make sure nobody around me end up using their service
