It will then offer seven-night cruises from 30 April. All 2022 and 2023 sailings are currently available for booking.
The line has also added the Greek city of Thessaloniki to its seven-night "Idyllic Aegean" itinerary, which will call at Mykonos, Santorini, Crete, Rhodes and Kusadasi in Turkey. Prices start from £759pp.
Celestyal’s seven-night "Eclectic Itinerary" will call at Kavala, Thessaloniki, Santorini, Volos and Istanbul. Fares come in at £759pp.
The end of 2022 will see the return of the line’s seven-night "Three Continents" itinerary, with calls in Greece, Turkey, Israel, Egypt and Cyprus.
This will be followed by two holiday voyages, a 10-night Christmas sailing calling at Thessaloniki, Izmir, Rhodes, Limassoland, Alexandria and Haifa and an eight-night new year sailing to Heraklion, Santorini and Kusadasi with an overnight stay in Istanbul, which costs £979pp.
Both itineraries can be combined for an 18-night holiday with fares from £1,739pp.
Celestyal’s chief commercial officer, Leslie Peden, said the line is "optimistic" that its destination-centric itineraries will continue to be well received by its core audience.
"Our confidence is supported by strong levels of interest, inquiry and bookings already for these itineraries next year and into 2023, which has been the catalyst to returning to year-round cruising," she added.
