Airlines efficiency as a ratio of input and output operating indicators is a frequently researched topic. This paper presents a new perspective on the issue - the efficiency of European groups of airlines. The air transport market is complicated. Competition and various influences are reflected in changes in the industry. In Europe, there has been a consolidation of the industry, with several companies joining together to form a single holding structure. The work examined the efficiency of the Easy Group, Ryanair Group, Lufthansa Group and Air France-KLM Group. Available seat kilometers, available ton kilometers, and number of aircraft were used as input parameters. Number of passengers, revenue passenger kilometers, revenue ton kilometers, and total revenues were used as outputs. Annual data was collected for the 2009–2022 period. All calculations were performed using DEAFrontier Software. The effectiveness of the groups studied varied over the period. Easy Group showed inefficiencies in 2011 and 2012. Ryanair's group parameters are inconsistent between 2011–2015 and 2018–2022. The Air France-KLM group had only one inconsistent year, 2016. The Lufthansa Group can be considered the most efficient without a deviation between achieved output parameters and the optimal level of efficiency.

The aim of this study was to quantify the impact of the Corona Crisis on the operational performance of the largest European Airlines. Due to the consolidation of the industry, it is not possible to talk about individual companies, but about groups of companies cooperating within a holding structure. This also posed a major limitation to the work due to data availability and integrity. The analysis focused on 5 airline groups selected based on the number of passengers carried: Lufthansa Group, Ryanair Group, Air France-KLM Group, IAG Group, Easy Group. The article contains an overview of data availability and a list of airlines belonging to each group. The operational performance of the airlines is defined using basic Key Performance Indicators. In this research 4 indicators were used: number of passengers carried, available seat kilometres (ASKs), revenue passenger kilometres (RPKs) and load factor (LF). The data was collected for the period 2013 to 2022. Number of passengers and LF is presented as net values development and as annual % change in graphs. ASKs and RPKs indicators, as they are only available for the fiscal year (it does not coincide with the calendar year) for low-cost airlines, are processed on year-on-year changes with the relevant decrease indicated in colour. ASKs represent a supply of groups, RPKs a demand, these performances are listed in the ranking. The results show how the performance of each group evolved before (2013-2019), during the pandemic (2020, 2021) and in 2022 marked as a recovery year.

This article presents a project proposal that was created in response to a competitive call from the Czech research support agency in the area of Increasing the Resilience of Society to Disinformation. We consider the most effective strategy for achieving this goal to be accessible interdisciplinary education – knowledge shared by the so-called Opposite Side Method. The idea uses the acronym INEDCO (INterdisciplinary EDucation COncept). It is an innovative form of education for the general public through the offer of knowledge. This set of knowledge will provide the society with a level of knowledge that eliminates/minimizes the tendency to believe delusions. The basic idea is elaborated in the form of a design structure, the second step is the methodology, and the third stage is the implementation of the project in the field of aviation. This proposal has a high potential to create a top team of researchers and produce applicable results in the long run. The essence of the project is interdisciplinarity and the collaboration of several universities at national as well as international level is essential to achieve the objectives. The concept of a shared and freely accessible INEDCO education to be the targeted opposite to the disinformation scene originated at the Department of Air Transport. Aviation is one of the fields that is a medium of hoaxes. As an institution with technical, technological, and methodological education in a very complex and difficult sector, we see the need to contribute to improving the level of knowledge and pacifying society through education.

The article's main purpose is to describe the proposed Methodology, which aims to present an approach to expressing the value of the air transport industry in the Czech Republic. This approach methodically divides the primary and secondary effects and finds metrics based on which the value of the air transport can be quantified. The proposed approach is based on equivalent methodological materials by ICAO, FAA, and other organizations describing and analyzing the value of air transports. The calculations are based on open data sources as well as data that are available by request. The methodology also proposes collecting new data to complete the picture of the value of air transport.

The initial motivation for studying and researching air transport socio-economic impacts is quantifying the value that air transport brings to the Czech Republic. The main challenge is to explore a methodology that would describe the macroeconomic and microeconomic relations within the Air transport industry. These relations will define the directions of the market forces flow and thus the Czech Republic’s value. The authors of the paper use an approach that follows methods and standards for collecting and processing economic and statistical data introduced by the International Civil Aviation Organization (ICAO), Eurostat, and the Czech Statistical Office (CZSO). The authors incorporate economic definitions and standards published by the United Nations under the World Trade Organization (UNWTO) and other accounting and statistical entities, which results in creating a methodical description of chosen relations. The methodical description leads to the quantification of the value. In a practical sense, it is a matter of determining the origin of the data sets according to which the selected relations will be defined. The paper focuses on the expression of Air transport’s primary and secondary effects and the description of the proposals, which will be part of the methodology.
