English is an international language which is very important for smooth bilingual interaction. Along with the times, the ability to speak English is required in all aspects of life to develop. One that is experiencing rapid development is the air transportation industry, which has a similar impact on the development of the airport aspect as a facility for providing aircraft transportation services. One of the important airports in the Riau Archipelago is Batam's Hang Nadim Airport. The airport was officially opened to the public on January 1, 1995 under the name "Hang Nadim International Airport. Since then until today, Hang Nadim airport has grown rapidly and has become one of the largest and busiest airports in Sumatra. With the rapid development of Hang Nadim Airport This, of course requires the use of an international language, namely English as the most commonly used communication medium. It has become a must for airport staff to be able to master English for the smooth operation of the technical process of aircraft and air flight systems. All airport workers are required to have good English language skills. it is appropriate to create conducive working conditions, but in reality on the ground, not all staff who work at airports have basic English skills, especially regarding the basic conversation part in English at the airport. If they are not equipped with basic English skills then they will not be able to speak English. can work optimally. Therefore, it is very important to initiate a dedication to provide a basic introduction to English for staff at Hang Nadim Airport, Batam City, Riau Islands.

Taking logistics time, logistics cost, and carbon emissions as optimization objectives, air transportation is included in the cross-border logistics paths optimization of multimodal transportation. Considering the scale effect of transportation, a multiobjective optimization model of cross-border logistics paths including road, water, railway, and air is constructed. The problem of cross-border logistics paths along the “Belt and Road” regions for cities in inland is studied via the NSGA-II method. The research results show that Chengdu and Xi’an should bear a large number of cross-border air transportation and be constructed as the national airport-type logistics hub. The foreign destinations of cross-border air transportation are distributed in different regions, mainly in Eastern Europe and Eastern Central Europe. The optimization result shows that if there is a 1-fold increase in logistics cost, the logistics time can reduce by 1.37 folds after the cross-border air transportation joins in the model. Such a result has effectively guided the transition from cross-border water transportation to cross-border air transportation.

Aviation has been hit hard by COVID-19, with passengers stranded in remote destinations, airlines filing for bankruptcy, and uncertain demand scenarios for the future. Travel bubbles are discussed as one possible solution, meaning countries which have successfully constrained the spread of COVID-19 gradually increase their mutual international flights, returning to a degree of normality. This study aims to answer the question of whether travel bubbles are indeed observable in flight data for the year 2020. We take the year 2019 as reference and then search for anomalies in countries’ flight bans and recoveries, which could possibly be explained by having successfully implemented a travel bubble. To the best of our knowledge, this study is the first to try to address the identification of COVID-19 travel bubbles in real data. Our methodology and findings lead to several important insights regarding policy making, problems associated with the concept of travel bubbles, and raise interesting avenues for future research.

The marketing activity of a modern airline is quite diverse. Under the conditions of an oligopoly, airlines develop their business in competition for a passenger.In modern conditions in Russia, the use of dumping methods of the early 1990s is very ineffective. There are no weak airlines left on the long-distance air transportation market, and in regional markets large companies lose to small regional carriers due to the high cost of performing flights on large-capacity aircrafts of the airline’s fleet.Generally, non-price methods of competition come out on top. Flexible tariff policy, advertising, and high service in servicing passengers remain leading traditional methods of competing for a passenger.This article is devoted to the study of another marketing method for attracting passengers, or rather retaining passengers on the airline’s flights, which is development of bonus programs, frequent flyer programs. PJSC Russian Airlines (Aeroflot) was chosen as the object for the study. The subject of the research is the «Aeroflot Bonus» program.The objective of the study is to study the cost of the program. For research purposes, this is the value of the frequent flyer program point. The problem proposed to be solved is to determine the amount of expenses for implementation of the bonus program of frequent flyers. When solving the problem in its staging part, the assessment is not limited to direct costs associated with the costs of marketing efforts in the form of costs for organising a special advertising department, issuing bonus cards, software, and wages. The estimation refers also to indirect costs in the form of unreceived proceeds from free bonus tickets. Besides, a rough estimate has been made of the airline’s hidden costs due to an unpaid seat on the plane. The study conclusions indicate that hidden costs will be taken into account in calculating the cost of a flight and the bonus program has a right to exist.

Blended wing body is a fixed wing aircraft which are smoothly blended together with no clear dividing line and no distinct wings also be given a wide Aerofoil shaped body. The future transportation is of aircrafts will incline towards the aerodynamically efficient and capable of carrying large number of passengers over long range and environmental benefits is the main paradigm in the design of aircraft BWB has a high lift to drag ratio which increases the CL max and velocity of the airplane with high load factor and high economy compared with traditional aircraft. Evacuation pressure or the cabin pressurization is the major issues in most of the designs with the minimum aerodynamic lift coefficient and drag coefficient. On the other side of the trend is towards the increasing cruise speed. High speed flow is connected with overcoming of intensive drag rise accruing due to existence of intensive shock, closing local area of supersonic flow. Increase of flight Mach number is possible only by using flow control methods and through affecting the shock increases of aspect ratio leads to increase of lift coefficient corresponding to maximal lift to drag. High bypass ratio engines have smaller fuel consumption and lower noise level but have negative effect on flow around airframe including take-off and landing phases. The necessity of solving problem of intensive aerodynamic heating of surface element of flight vehicles and by ensuring of their stability and controllability and also by need of implementing of high-volume tanks for hydrogen fuel and super high bypass ratio engines.

ABSTRACT The purpose of this study was to determine the effect of the alleged cartel practices carried out by the airline PT Garuda Indonesia, Tbk, namely by the increasingly high price of airline tickets and how their impact on the stock price movement itself. This practice is not permitted in Indonesia and almost all countries in the world, but this becomes very dilemmatic in the current aviation business if the ticket price is not raised the company will bear substantial losses but on the other hand consumers are very disadvantaged and can sacrifice the country's economy if countries that depend heavily on air transportation such as Indonesia. Considering that PT Garuda Indonesia, Tbk is a state-owned company of the Republic of Indonesia which has been listed on the Indonesia Stock Exchange under the GIAA stock code, whether news of alleged cartel practices by GIAA could affect the public investors in the capital market in making a decision to make a selling or buying transaction on GIAA shares.Keywords: cartel practices, garuda indonesia, capital markets
