A number of clues here that it's a scam and sod all to do with QR.
Hold your mouse over the URL's and they all go to addresses like rediffmail.com/cgi-bin/red.cgi?red=http%3A%2FFwww%2EMonstergulf%2Ecom
Then 'qatarsairways (at) gmail.com' ...... I dont think so.
Fortunately the majority of the people who try these scams are too stupid and illiterate to make them any more convincing.
