Good amount of work has already been done to improve passenger comfort in aircraft during flight. For improved passenger comfort, besides providing comfortable seats and a good environment and entertainment, the services inside aircraft have improved and should keep improving because of the newer problems creeping up daily in the air transportation of passengers. Services inside the aircraft include:

- Looking after passengers-old people, and children
- Keeping passengers informed and giving instructions from time to time audio and printed communication
- offering pillows and blankets
- Showing seats
- Various services and ensuring that there is no possibility of a complaint
- The distribution of food articles onto individual plates
- The serving of breakfast, lunch, tea, dinner, coffee, cigarettes, and drinks
- collection of these utensils back from the passengers
- storing them when they are filled or empty
- Storage of left-overs and disposable items like empty tin cans, bottles, etc.
- When the flight is long and nonstop, cleaning part or all of the cutlery for reuse during the flight is recommended.
- Heating or keeping food articles cool

Nowadays, it is clear that all international airline corporations are competing fiercely with one another and are essentially fighting for survival. With the introduction of Jumbos, the problem has become even more critical. For profitable operation of these aircraft, it is necessary that aircraft take off with a certain minimum percentage of the total capacity (breakeven point), depending on operation cost, fare structure, overheads, etc. Various airlines have already taken steps to attract passengers, such as slashing round-trip air fares. But there are limitations to it.
