1861 A Difference In Class

The more Miguel and Khiger saw, the more explosive their minds became. 

The first thing they got to know was that there were 4 Main class groups when flying: 

-Economy/Coach Class: That offers basic accommodations,

-Premium Economy Class: That was slightly better than Economy,

-Business/Executive Class: Typically for those traveling for business purposes,

-First Class: Which is just a class that offers pure luxury.

...

To be honest, when they saw the images of several Economy class seats and areas, they were quite surprised and already felt it looked luxurious.

Understand that unlike Earth, all humans had certain height ranges and were more or less the same… In this world, there were people like the Giants who were so tall they would definitely not fit in any economy class seats offered on Earth. And it wasn't proper to now force them to buy business or first class seats just because of this.
