How to find fare "buy one get one free"?
Im trying to find flights with TG in august from ARN, CPH or FRA to BKK in biz class that qualify for the "buy one get one free" campaign. Seems like FRA is about 2014€ +tax but I cant find any of these fares that shows that the second person is free. Any clues on how to find em? Best for us would be ARN.
