The beginning of 2021 found airline stocks rise significantly as mass vaccination programs and the minimization of travel restrictions brought about an increase in passengers and an increase in corporate revenue.

Analysts' expectations for a hot passenger summer have boosted buyers, with sector’s returns being the best for 2021. However, the Delta mutation has caused another upheaval and there have been many cancellations in July and August. These months are also one of the best for these companies. As a result, stocks have adjusted significantly and perhaps excessively in relation to the real outlook of travel traffic.

It remains to be seen whether the latest uptrend, which is accompanied by strong investment interest, will manage to reverse the uptrend and lead again to an attempt to approach the recent highs.
