Sorry to say it that blunt, but it's pretty stupid to create a promotion that can be abused that easily. Unless they are very well aware of that and it's just about creating a hype. They are targeting an audience that is clearly tech and aviation savvy. No surprise they are connected. BTW, I don't see anything in the terms that would indicate one needs to be personally at the airport, neither that one needs to be there and fly with LHG.
