Air traffic is the youngest transport branch that allows passengers to cover long distances in the shortest possible time. Today, there are traditional and low-cost airlines, each with its own specific advantages. Croatia Airlines is the only Croatian national airline. Airlines' communication with passengers takes places through marketing channels, which are defined and explained in detail in this paper. At the beginning of 2020, a crisis arose in the world caused by the COVID-19 virus, which in a very short time spread to a pandemic. The crisis also affected aviation industry so airlines found themselves in unfavorable situations due to numerous canceled flights. The aim of this paper was to show, through qualitative and quantitative analysis, what kind of content Croatia Airlines communicates to its passengers through digital marketing channels and how often it does so. The analysis covered the period from the beginning of 2019 to the end of 2021 in order to compare the difference in communication before and during the COVID-19 crisis. The research showed that in the first year of the crisis, there was a drop in the annual number of posts, that is, a decrease in the frequency of communication, which gradually began to increase in the next year of the pandemic.
