25 United Airlines flight attendants protested at the Hong Kong Airport yesterday over the termination of United Airlines' pension plan.

The airline's employees were holding similar demonstrations in Tokyo, London, Frankfurt, Germany, and 14 U.S. locations.

Some of the protesters held signs that said, "Chaos is coming to Hong Kong" and "Save our pension." They marched outside the airport and near the check-in counters.

United Airlines said in a statement that it wants to reach agreement with the union and that operations at the Hong Kong airport would not be affected.
