     It was graduation day at Etihad Training Academy, where the national airline of the United Arab Emirates

holds a seven-week training course for new flight attendants.

     Despite her obvious pride, Ms. Fathi, a 22-year-old from Egypt, was amazed to find herself here. "I never

in my life thought I'd work abroad," said Ms. Fathi, who was a university student in Cairo when she began

noticing newspaper advertisements employing young Egyptians to work at airlines based in the Persian Gulf.

     A decade ago, unmarried Arab women like Ms. Fathi, working outside their home countries, were rare.

But just as young men from poor Arab nations poured into the oil-rich Persian Gulf states for jobs, more

young women are doing so.

     Flight attendants have become the public face of the new mobility for some young Arab women, just as

they were the face of new freedoms for women in the United States in the 1950s and 1960s. They have

become a subject of social anxiety and fascination in much the same way.

     For many families, allowing a daughter to work may call her virtue into question. Yet this culture is

changing, said Musa Shteiwi, a sociologist at Jordan University in Amman. "We're noticing more and more

single women going to the gulf these days," he said. "It's still not exactly common, but over the last four or

five years it's become quite an observable phenomenon."

     Many of the young Arab women working in the Persian Gulf take delight in their status as pioneers, role

models for their friends and younger female relatives. Young women brought up in a culture that highly values

community, have learned to see themselves as individuals. The experience of living independently and working

hard for high salaries has forever changed their beliefs about themselves, though it can also lead to a painful

sense of separation from their home countries and their families.
