company introduced a new livery, based on the Union Jack, to emphasise its British heritage, and in 2015, the 143,730-ton newbuild Britannia joined the fleet. Adonia transferred to Carnival's new Fathom brand in 2016, returned in 2017, and then departed the fleet permanently in 2018. In 2019, the company's first newbuild, Oriana, also departed the fleet. In March 2020, P&O Cruises joined every other cruise line worldwide in suspending passenger operations as a precaution against the emergent COVID-19 pandemic. This led to the departure of Oceana in July 2020, as Carnival sold multiple older ships across their fleets in order to increase liquidity. It also delayed the arrival of the 184,089-ton newbuild Iona from May 2020 to October 2020. Iona was the UK's first ship to be powered by liquefied natural gas (LNG) rather than fuel oil, which was intended to make her more environmentally friendly. The company resumed passenger operations in June 2021, after fifteen months, with Britannia being the first of the fleet to sail, followed by Iona in August 2021. In March 2022, P&O Cruises suffered a public backlash following a mass firing of staff by P&O Ferries, another former subsidiary of P&O. They subsequently embarked on an advertising campaign in national newspapers and on social media in order to clarify their separate ownership. Arvia, a sister ship to Iona, joined the fleet in December 2022. Golden Cockerel P&O Cruises awards the company's Golden Cockerel trophy to the fastest ship in its fleet. The trophy is currently held by Aurora, which achieved a speed of 25.7 knots in April 2019. It was previously held by the first Oriana until her retirement in 1986, Canberra until her retirement in 1997, and the second Oriana until her retirement in 2019.
