Abstract Subsidizing air mobility for Canary Island residents may have an unforeseen impact on regional air carrier route development and this could exacerbate congestion in airports that operate near to their maximum threshold. Reginal routes often require the use of small aircraft such as those from the ATR (Avions de Transport Régional) family. These aircraft types have [some specific characteristics related to its time performance. If airports manage a large proportion of ATR aircrafts, one of their main activities, such as landing and taking off operations (LTO), may become congested, and affect airport capacity. Air carrier economies might be negatively affected because of delays in airport operations. For instance, air carriers’ fuel costs might rise due to aircraft’s increased LTO time. This paper seeks to analyze the impact of regional aviation route development for the Canary airport network; specifically, the effect that it has on airport capacity and air carrier economies.

The Impact

The coronavirus (COVID-19) pandemic, which started in China as of December 2019, has spread all over the world and caused different adverse effects in each country. The coronavirus has affected millions of people around the world and caused thousands of deaths. The pandemic, which causes us to question our knowledge to be true and is a new factor that should be seen as a risk in future planning, has brought new regulations in all vital activities. The fact that airline transportation is one of the sectors most affected by coronavirus determined the scope of the study. Within the scope of the study, exploratory case study was preferred and how airport operations were affected by the COVID-19 pandemic was illustrated.

The Ideal

The objective was to provide a useful computational tool for assessing the impact of condenser tube modifications on power plant condenser performance and unit heat rate, which directly affect the operating cost. To achieve this, a methodology was utilized to evaluate the economics of condenser modifications based upon design and economic information. The numerical model of condenser performance was developed using the Heat Exchanger Institute method and the Resistance Summation method. The software calculates results based on both methods but this paper will only discuss the results from the Heat Exchanger Institute method for the case study. Since condenser performance has a direct impact upon fuel costs, heat rate, power production and emissions, this computational model can be used to assess the economic impact of a proposed condenser tubing replacement over a specified service life. A case study will be discussed concerning a condenser tube replacement project that was analyzed to determine the ideal replacement tube material for the relevant parameters associated with this particular unit.

Event Study Methodology

In response to increasing fuel costs, airlines began introducing baggage fees as a new source of revenue, fees which have since been increased. In this study, an event study methodology is used to examine the impact of these announcements on airline stock prices. The results indicate that the initial announcements led to negative abnormal returns for the announcing firm and other competing airlines, as they were interpreted as a sign of industry weakness. However, the results also show that subsequent increases in baggage fees, which had been shown to positively impact the airline’s financial performance, are associated with positive abnormal returns.
