According to data produced by the firm for the World Travel Market, in July, August and September, global air traffic is set to reach 65% of where it was before the pandemic in 2019.
However, the revival is "patchy", with some parts of the world performing better than others and some types of travel, particularly beach holidays, being more popular than urban city visits and sightseeing.
The region on course to recover most strongly is Africa and the Middle East, with arrivals in Q3 expected to reach 83% of 2019 levels. It is followed by the Americas, where summer arrivals are expected to reach 76%, and then by Europe, 71%, and Asia Pacific, just 35%.
