Preparations for Flights
A: Passengers should make preparation for taking flights after
having decided to travel by air and have a clear idea about
Choosing Aircraft Type
There are different types of aircrafts to be choosen and passengers
could choose between different types of aircraft and flights
with airline companies,flight ticket offices or travel agents.Generally
speaking,the more advance the aircrafts are,the better comfort
will be provided on board.
Passengers could choose different type of tickes between first
class,business class and economic class.The first class and
business class seats are spacious and comfortable.More space
for movement and better flight services will be provided for
these two types of passengers,but the ticket price is also higher,which
is 130% to 150% of the economic flight tickets.But passengers
should note that the safety factor of passengers is not related
to the price of their tickets.
Making choice no seats is also important ,and will affect the
comfortableness of passengers.Generally speaking.there is better
stability of seats between the wing and front end of the aircraft.For
passengers who are concerned about bumping caused by air currents,they
are recommended not to choose seats at the rear end of the aircrafts.For
passengers who wish to have more space for movement of legs
and feet,they are recommended to choose the seats that are the
front rows or close to the emergency exits.Passengers who may
move frequently could choose seats near the passage.When feeling
uncomfortable at flights they could stand up or move around
without causing too much disturbance to other passengers.

consciousness of even danger of life.The table below show the
time human can sustain under the condition of pressure lost
and oxygen shortage.
The oxygen mask is a lifesaving device to provide oxygen to
passengers in case of emergency.Under the circumstance of losing
pressure inside the cabin,the masks will fall automatically
from the cabin roof and passengers should put them on until
the aircraft is lowerd to a height which safe for the breathing
of passengers.There are sufficient number of oxygen masks on
boards every flight.In addition to 1 mask for each passenger
there is another spare one for each row of seats to prepare
