"They're really doing it right," said Jeannie Childs, of Lihu'e, a Kaua'i-to-Honolulu passenger. "They've got extra people on duty and they have people out front explaining the new rules. They're really friendly. And the wait is not that long."

Most passengers were forewarned of the additional security precautions, but a few appeared surprised, she said.

"There are some people that did not know anything about this, and they were upset," she said.

Kaua'i Visitors Bureau director Sue Kanoho said her agency was prepared to send personnel to the airport to assist visitors if delays and extra-long lines occurred, but had not heard of difficulties requiring additional passenger assistance.

"We're trying to warn visitors as early as possible," Kanoho said. "We've got fliers at all the rental car agencies, and we're asking vendors selling liquid items to warn people they won't be able to take them on the plane with them."
