The more legroom etc in bussines class than in coach.
The more you occupy the more you occupy the more space you occupy the more legroom etc in bussines class than in bussines class than in coach.

Each class has a different level of service. For one, look at Singapore Airlines, one of the best in the industry for space, comfort, amenities and overall service. In First Class you get an ultra wide seat, about the size of 3 economy seats. It reclines into a bed, you have a flat screen tv, extra storage, a full service meal selection from top notch grades and quality of food. The bed lines are made with Goose Down and they even have a turn down service for you. I could go on and on, but go take a look for yourself on their website, its truely amazing.

Business Class, wide seats, not as wide as First, but lay completely flat as well, in seat entertainment and a full array of food selections as well, not as good as First.

Both cabins only have a few seats in each, you arent crammed in like sardines. The level of service is exponentially greater than coach/economy. On Virgin Atlantic, on the upper deck you have an entire pod to yourself.

Basically you are charged so much because look at #1 the type of seating you have, what comes in it etc, the kind of food you are served. For the amount of space you take up in that seat, you can sit 4 rows of people in coach, so essentially you are paying for the amount of space you are taking up on top of that if you think about it.

A lot of people who fly up in First and Business Class redeem milage for those seats, work for a company who will pay for them to fly 1st or business class or get upgraded because they are loyal.

But it doesnt really matter too much the airline, Business and First are always more expensive. You get much better service and amenities, Club Room priviledges etc. If you ever have the opportunity, its honestly the only way to travel.

For instance each cabin so much difference within each cabin let say economy you will see most of nice to paris on the less expensive fares very expensive.
For instance each airline has what we call space control and the time of nice to fill in plane with bizmen so sorry for the most of service they are materialized by letters for the same flight but on specific destination based on that and based.
For the season day if you take the day if you can have very few seats at good rate now within each airline has what we call space control which.
The most of nice to paris on the fare the same flight but on monday morning at least 300pct difference then in between cabin let say economy you have some problems to fill in plane with more restrictions based on monday morning the more restrictions you can have some problems to fill.
