The event will be held on Thursday (4 March) to coincide with the originally planned date for the association’s annual dinner ahead of a "year of celebrations" set to play out during "the most momentous time for global travel".
The SPAA was founded in 1921 and is the world’s oldest organisation representing travel agents; it currently has 120 members across Scotland, and 92 associate members.
Members and associates are invited to join the event from 7pm on Thursday, with the association’s face-to-face centenary dinner fixed for 9 September.
