Summit will cancel its March 29 cruise out of Port Everglades and delay (and shorten) the next scheduled voyage, an 11-day trip, into a seven night sailing that departs April 12.
Infinity loses two sailings -- both from San Juan, scheduled for April 13 and 20 departures.
There are more changes as well -- port swapping and the like -- so if you are booked in April on either of the two ships call your travel agent or Celebrity at 1-888-305-4626 for details.
According to a Celebrity statement, the ongoing troubles relate to pods involving ball-bearing units that are wearing out prematurely. This slows ship down, resulting in missed port calls.
Both ships will receive repairs at the Grand Bahama Shipyard in Freeport, Bahamas.
