Out of curiosity, were those free with or without taxes/fees?
One of my friends about 12 years ago found round trip tickets from NYC to Egypt for $0 + taxes and fees. Fees came to about $100-$200 or so. He immediately bought 10 tickets for himself and friends. So an amazing deal, but still not free when considering taxes and fees.
Those were all-in. The $0 Air Canada one they actually called me and said that technically there was no contract of carriage because there was no money exchanged, but they let me have it anyway. And actually I remember now, it was $200 to Romania, and we ended up paying $230 more to get to turkey on a standard ticket. The Bucharest ticket was surely supposed to be $2000.
