The $100 onboard spending credit will also be available to active, retired and veteran members of the military.
The offer can be redeemed on seven- to 28-day cruises through to May, including Collectors’ Voyages to Norway, the Baltic, Mediterranean, Iberia and transatlantic. Reservations must be made by 15 March to qualify.
Onboard, the credit can be used for shore excursions, spa treatments, beverages, speciality dining and gift shop purchases.
HAL president Gus Antorcha said the company wanted to "recognise those who continue to give incredibly selfless service with an extra ‘thank you’ for answering the call".
"Our hope is that while they are relaxing on holiday with us, they can enjoy their time onboard just a little more," he added.
