From 4am on Friday (7 January), anyone arriving into the UK will no longer need to test negative for Covid-19 prior to departure.
They will also no longer need to self-isolate upon their arrival until they get a negative Day 2 test result, while the Day 2 testing standard will be lowered from PCR to lateral flow from 4am on Sunday (9 January).
SPAA vice president Mike Tibbert said the move was "hugely welcomed by all of us in the Scottish travel sector".
"Hopefully we can start to see the restoration of confidence in international travel, which is such a valuable sector for the entire Scottish economy," he added.
