Bought tickets on January 2020 (for 836$) but my flights were cancelled due to COVID-19. They sent me a email telling me Ill have a future travel credit, which Im ok with it. I called them several times by the end of 2020 to make sure my travel credit were still available for at least a year, they kept telling me everything is ok BUT I still havent received my voucher. They told me they would send me the voucher or code to make a new reservation but I still havent got it. It was already difficult to have someone on the line but now its just impossible. I waited over two hours last time to be finally hunged up. User's recommendation: Do not use Flightnetwork.
