Seatrade News reports that the season was canceled "due to the ongoing uncertainty around when international operations might fully restart in this region."
Cruise lines plan their ships' itineraries years in advance. The logistics involved in arranging ports of call, tour operators, fuel, and supplies require that time. The pandemic has forced companies to make sudden changes to their itineraries out of necessity.
Celebrity Cruise has now announced that they have decided to cancel its 2023-2024 Asia season on the Celebrity Solstice. This cancellation will affect sailings departing from September 16 through April 21.
The Solstice will instead sail the now very crowded Mexican Riviera. According to Cruise Week, Solstice will be assuming the deployment planned for Celebrity Millennium, which will be moving to the Caribbean.
According to a company spokesperson, "We have made the difficult decision to cancel our Asia season due to the ongoing uncertainty around when international operations might fully restart in this region."
