I had been using flight hub for 2 years already and they already changed my flights 3 times. Once they ask you to confirm the change of flights you don't have any other options ( cancel or use other options) so you are basically in bad shape if you already accounted for enough time during the layover. Hotline is more than happy to help you but won't be able to explain to you what to do if you are not satisfied with the flight change.My advice don't accept any change of flight. Looking at the 1 star review, i am not the only one in this case.
