There was a very similar promotion running in Australia last year where you could get free return flights for buying six bottles of wine (minimum cost around $68). They also required sending in paper forms and nominating three destinations and three sets of dates. I went to Bali on that deal.

That said a number of people missed out due to the confusing processing and a page where it requested ID (drivers license or passport) but if you only provided a drivers license they refused to accept any international destinations, therefor you hadn’t nominated 3, therefor you got nothing. Of course it would have been trivial to ask for passport details after the fact but obviously the intention was to deny those who tired to claim on any technicality possible. The passport requirement wasn’t mentioned in any terms either which makes it even more dodgy.
