The Celebrity Equinox landed crucial supplies in Antigua during a call on Sept. 12.
The 2009-built ship was able to assist the location, which neighbors Barbuda, which was hit hard by Hurricane Irma.
"Our @CelebrityCruise Equinox in #Antigua brings 1st assistance to #Barbuda #HurricaneIrma victims makes us so proud. #Caringforeachother," wrote President and CEO of Celebrity, Lisa Lutoff-Perlo, in a post on Twitter.
It is one of many examples of recent aid runs by the cruise industry. Bahamas Paradise Cruise Line also announced today it would open the Grand Celebration for free hot meals for first responders as well as modestly-priced accommodations.
