American Safari Cruises launched an "Even More Beautiful at 50" promotion to commemorate Alaska's 50th anniversary of statehood.
Under the initiative, customers will be offered up to $500 off on any of the line's four itineraries in Alaska.
In addition, travel agents who book staterooms by Dec. 5 will receive a $50 bonus per booking and be included in a January drawing for a free Alaska cruise.
The campaign will include five weekly e-mail messages sent to agents between Nov. 11 and Dec. 9 each focusing on a different aspect of travel to Alaska and ways agents can sell the company's cruises to the state.
