This means some passengers are being notified their trips are canceled.
Queen Victoria and Queen Elizabeth
The impacted voyages are on Queen Victoria from Southampton to the Mediterranean, Northern Europe and the Norwegian Fjords, and on Queen Elizabeth from San Francisco to Vancouver and Alaska.
A company spokeswoman did not have the number of voyages that are affected.
COVID-19 travel disruptions
'The wider impact of COVID-19 is affecting hospitality and disrupting airlines and as such this is impacting the number of crew members we are able to get to our ships,' Cunard said in a statement.
'We naturally want to ensure that all guests across the fleet experience the high standards of service onboard that they would expect from Cunard and which we are committed to delivering. We are therefore limiting the number of guests sailing on Queen Elizabeth and Queen Victoria as we build crew numbers back up. Unfortunately, this means that we need to cancel a number of existing bookings.'
Cunard will be contacting passengers over the coming weeks and will automatically process a full refund and extend a future cruise credit worth 25% of the fare paid. This can be redeemed on any future cruise booked by Dec. 31, 2024.
