DO NOT USE THIS TO BOOK ANYTHING!!!! The worse customer service I have ever experienced in my life. I booked a flexible ticket, and when I tried to change the date (after hours on the phone to non-English speaking call centres) I came to find out the date had in fact not been changed. I only discovered this because I rang the airline. When I raised the issue with Gotogate they refused to change the flight without me having to pay the fare difference AGAIN. I had already paid the fare difference when I changed the flight. On top of this you can't complain until 2 months after your return journey. You have been warned....it is not worth the cheap price of the flight and a flexible ticket is one huge scam.
