Carnival Cruise Line will swap out its two New Orleans-based passenger ships with other ships beginning in May 2019.

The Miami-based company said Thursday it plans to deploy its 2,974-passenger Carnival Valor from Galveston, Texas, to New Orleans. It replaces the 2,754-passenger Carnival Triumph on year-round four- and five-day cruises out of the Crescent City.

The 2,980-passenger Carnival Glory, now in Miami, will replace the 3,646-passenger Carnival Dream, sailing year-round seven-day cruises out of New Orleans.

Together, the Valor and Glory are expected to carry nearly 400,000 passengers per year from New Orleans, the company said.

Carnival President Christine Duffy said New Orleans is among the company's most popular and fastest-growing home-ports.

The Valor will be the largest ship to offer a year-round short-cruise schedule from New Orleans, the company said. The ship underwent a multi-million-dollar renovation last year.

The Valor will rotate four-day-long cruises to Mexico that depart Thursdays and visit Cozumel with five-day voyages, departing Mondays and Saturdays and calling on Cozumel and Progreso.

Seven-day cruises from New Orleans rotate among itineraries that include Mexico, Belize, Honduras, the Bahamas, Key West, Florida, Grand Cayman and Jamaica.
