Well, I have not seen the ad or heard any official comment but I am guessing it is a simple marketing effort that you would see anywhere else in the world. In fact, the slogan is so clean and simple that my guess is they ripped it off from another airline in Europe, NA or OZ!!!!
This is the exact type of advertsiing you would see from either a national airline anywhere in the West or from any of the upstart low costs trying to muscle into new markets and capitalize on a countries citizens pride.
So why should GF be any different in that regard. They are targeting the Bahraini narket with those ads and, since it is the countries airline, they have added some national pride which always helps with advertising.
But like I said - have not seen the ads so maybe I am wrong.
