Carnival spokeswoman Jennifer De La Cruz said that the Carnival Liberty, scheduled to end one voyage and start another on Aug. 11 from Civitavecchia (Rome), might be delayed to allow guests extra time to get to the vessel but currently there were no plans to alter the ship's itinerary. Carnival also contacted its guests about the newly prohibited items on flights from the U.S. and the U.K. 

Cunard spokeswoman Jackie Matthews said there were no changes to the Queen Mary 2's scheduled departure from Southampton Aug. 11 for its transatlantic crossing to New York. The QE2 departed Aug. 10 on schedule from Southampton for a 14-day Mediterranean cruise.  

Holland America Line changed the departure times on seven of its ships leaving ports in Europe, Vancouver, and Seward, Alaska, over the next four days. European departures are most dramatically affected, with the Amsterdam's embarkation from Copenhagen pushed back to Aug. 11 at 11:45 p.m. instead of 5 p.m., and the Prinsendam's departure from Lisbon at 4 a.m. on Aug. 15 instead of 5 p.m. on Aug. 14. HAL said it made the changes due to increased security measures implemented in airports worldwide to allow its guests additional time to reach the ships.

Norwegian Cruise Line has not made changes to any itineraries yet, but said it will continue to monitor the situation and advise of any changes on its Web site, www.ncl.com. It also has information on the site regarding new aviation regulations.

Princess Cruises spokeswoman Karen Tetherow said the Golden Princess departed as scheduled Aug. 10 and will return to Southampton, England, on Aug. 20.

Seabourn Cruises said the Seabourn Pride departed Copenhagen, Denmark, Aug. 10 "short a few guests" that will join the ship in Helsinki, Finland, said spokesman Bruce Good. He said two ships departing Civitavecchia, (Rome) on Aug. 12 and they will base any changes on events that transpire over the next few days.

Windstar Cruises pushed back departures on its next two sailings in Europe by two hours each. Both the Wind Star out of Athens and the Wind Surf out of Barcelona will leave at 7 p.m. instead of 5 p.m.
