In 2008, the British line introduced a no-smoking-indoors policy on three of its ships -- Artemis, Oceana and Ventura -- when the U.K. banned smoking inside public places. P&O is now following suit with its remaining three ships and its new-build, Azura, which joins the fleet next April.
From April 2010 smoking will no longer be permitted in any inside areas, including staterooms, onboard Aurora, Azura and Oriana. The ban will be implemented on Arcadia in May 2010.
Passengers who wish to light up will still be able to smoke on stateroom balconies and on certain open decks.
Earlier this year fellow Brit line Fred. Olsen also decided to stub out inside smoking across its fleet.
