Being from the Middle East, there is one GLARING reason for the recruitment of Gulf Air in Estonia. Many people are not familiar with the Middle East, the the traditional values that vary from country to country.
Let's start with the "north." The two major carriers of the northern Middle Eastern countries would be MEA
and Royal Jordanian. The daily culture and tradition of Lebanon and Jordan present an equality between men and women. This is reflected in the employment of Lebanese and Jordanian women on board the countries' respective national airlines. It is also quite often to see Lebanese and Jordanian flight attendants working on other foreign airlines that operate into Amman and Beirut.
In terms of the "south," more commonly known as the Gulf States, the situation is quite different. The societies there are much more conservative and it is seen as inappropriate for a woman to go and serve as flight attendant. Not only is this seen in the flight attendant industry, but it is quite often seen across the board (and I'm not saying there aren't any exceptions, I lived in Saudi Arabia for 6 years and encountered many female, Saudi professionals). Therefore, Gulf Air, Saudi Arabian, Emirates, Qatar Airways recruit for employment in various countries. When I lived in Riyadh and flew SV
frequently, it seemed as though most of the F/A's were Asian, specifically Filipino. The women they recruit come from cultures where it is acceptable to present themselves in front of strangers without having to cover themselves. Also, the requirements that they have set (not married, no children, etc) minimize the obligation of the airline. The flight attendants are offered glamourous lifestyles in the Middle East, and this is expensive for the airlines. If the flight attendants had "baggage," costs would run high. Furthermore, if there is a family who currently resides in the Gulf, with the husband already under contract with any company, airlines would not mind hiring an ex-patriat living with her husband and children. Why? Because the airline only has to provide the flight attendant with her pay, as she already has her accomodations in the Middle East made for her.
In order to operate as a worldclass airline, Emirates, Saudi Arabian, Qatar Airways, and Gulf air all need to have recruitment efforts (similar to the ones in Estonia).
And for the by-the-by, LTBEWR, you could not be any more mistaken.
