P&O Cruises will charter flights with Virgin Atlantic for Caribbean fly-cruises in winter 2017 and 2018.

The sailings will be on the cruise line’s smallest ship Adonia which recently returned to the line after sister brand Fathom ceased operations.

Flights will be available from Manchester and Heathrow with economy, premium economy and upper class seats available for the 14 and 28-night itineraries.

There will also be a number of economy seats available on existing Gatwick scheduled services.

P&O Cruises senior vice president, Paul Ludlow, said: “P&O Cruises is an iconic British brand delivering a truly memorable travel experience and so this partnership with Virgin Atlantic is an ideal fit for our guests, enabling them to begin their holiday in style.

“It will give our Adonia guests even more choice with the option of three departure airports and three cabins, including Virgin Atlantic’s exceptional Upper Class.”

Adonia’s 2017/18 Caribbean season will operate from November 3, 2017 until March 8, 2018 and include 14-night Eastern Caribbean cruises round-trip from Bridgetown.

Destination highlights include Mayreau the smallest inhabited island of the Grenadines, Bequia which is part of St Vincent and Santarem in Brazil which is situated in the Amazon River.

In November 2016, parent company Carnival Corporation confirmed the 710-passenger Adonia vessel would be returning to P&O Cruises.

This was due to the folding of social impact cruise line Fathom as a stand-alone cruise brand.

Social impact excursions, pioneered by the Fathom brand, were announced to be extended to six of the Carnival group’s other cruise lines instead.

The charters from Heathrow and Manchester include return economy seats in the cruise fare with upgrades to premium economy from £349 and to upper class from £799 per person.

The upper class experience includes a personalised, dedicated check in and security with access to the award- winning Clubhouse at London Heathrow.
