The price of Hawaiian Holdings Inc.'s common stock had its biggest decline in more than two months amid concern that a swine flu outbreak could result in people cutting back travel.

Shares of the parent company of Hawaiian Airlines fell 56 cents, or about 10 percent, to close at $4.79 today. The last time shares of Hawaiian Holdings fell 56 cents was on Feb. 10.

Other travel-related shares fell, with Host Hotels & Resorts Inc. seeing a 15 percent tumble and Delta Air Lines Inc., UAL Corp. and Carnival Corp. each losing 14 percent, Bloomberg News reported.

"Concerns about how broad-based the outbreak is have grown over the course of the day," money manager Douglas Cliggott said.
