To make a study of load factors more or less representative of something, it has to be linked to specific routes. And a number of factors have to be considered. For example, what I have observed is that load factors are consistently high on routes with large expat communities. And understandably so - many of those people spent a few months without seeing their nearest and dearest during the most severe travel restrictions. Holiday destinations are also way more popular than I expected during lockdown. As long as there aren't any draconian entry rules in either country, people tend to be quite willing to get away. Of course, not forgetting the fact that good load factors on a schedule that is anywhere between 40% and 70% of last year's still represent not-so-good absolute numbers...
