These sailings replace previously canceled Southampton round-trips.
22 cruises, late July through September
Regal Princess will offer 14 departures, July 31 through Sept. 23, while Sky Princess's eight cruises run from Aug. 30 through Sept. 28. Ports are Liverpool, Belfast and Greenock.
'While international travel remains uncertain, these new cruises mean that UK residents can take a well-deserved holiday around the UK. We are also delighted that our new cruises will offer the choice between scenic voyages and port-of-call itineraries where guests can visit the historic UK cities of Liverpool, Belfast and Glasgow,' said Tony Roberts, VP UK and Europe for Princess Cruises.
The MedallionClass ships offer touchless experiences via the OceanMedallion wearable that support new health protocols.
'Guests can make the most of our multiple dining options, order food and drink poolside, using the MedallionClass app, that can be delivered to you, and enjoy fantastic entertainment both day and night,' Roberts said.

Travelers have the opportunity to make their cruise all-inclusive by selecting the Princess Plus fare, which includes a premium drinks package, unlimited MedallionNet Wi-Fi and gratuities, for £30 per person per day.
All-inclusive fares for a balcony stateroom start at £539 for a three-night scenic voyage, £599 for a four-night cruise with up to one port and £999 for a seven-night cruise with up to three ports.
