We live in an age where saving time is more important than saving money. This is probably the reason that air transportation, which is reserved for reservation at high level or fully reserved, is now used by its competitors, that is, rail and road transport. Over the last few decades, the number of passengers has increased tremendously, and the countdown is still increasing.
A few decades ago, mature, developed and prosperous nations like the United States, Europe, Japan, Singapore etc. also had air connectivity with major local cities and international destinations. There are countries like Singapore and companies like Surbana Juroung which is engaged in building smart airport to facilitate modern men’s requirements.
