Asiana Airlines Inc., South Korea\'s No. 2 flag carrier, will allow female flight attendants to wear trousers, officials said Tuesday, ending decades of its skirt-only policy that critics say is discriminatory. Some of the 3,400 female flight attendants have applied for the new trouser uniform in the first such move since Asiana\'s foundation in 1988, Asiana Airlines spokesman Na Chul-hee said.
