The increase in output will reportedly showcase Saint Lucia as a destination which offers travellers "many experiences" beyond the beach.
SLTA said it will continue to engage with the trade via incentives, training and trade events.
The fam trips will showcase Saint Lucia’s "niches", such as romance, luxury, diving and small properties, as well as general itineraries to showcase the wider product.
The announcement comes after SLTA released its latest figures for the winter sun season, with arrivals seeing a "continued rise" with a 25% increase on 2020 year to date.
A total of 20,393 stay-over arrivals was recorded in October 2021, up 61% on 2020. October was also the UK’s most successful month for 2021 so far with arrivals just under 6,000.
Tourism minister Ernest Hilaire said the sustained regain is a "clear indication" that the island’s Covid-19 protocols and "well-targeted" marketing output has had a positive impact.
"Feedback from our visitors tells us that when they come to Saint Lucia, they have a wonderful time and feel reassured with how we are managing the tourist experience during the pandemic," Hilaire added.
From 1 November, British Airways returned to daily flights to Saint Lucia and from 18 December Virgin Atlantic will offer three flights a week from Heathrow.
