The vouchers can be claimed for the first 150 new Alaska bookings made during March. A range of seven, 14 and 18 day voyages to the destination will start from 27 April.
HAL director of sales Wendy Lamich thanked the line’s travel and tour operator partners for their "loyalty and support" in selling the brand’s Alaska product.
"2022 is proving to be an excellent year for UK Alaska sales – but there’s more work we can be doing to make our 75th year of operating in this spectacular destination a bumper one," she added.
To qualify for the scheme, agents must email SalesSupport@hollandamerica.co.uk with a clients’ booking reference.
