Frequently Asked Questions:
Why
was Airline Safety Records Created?
Airline-Safety-Records.com was created
to act as a safety "report card" on America's airline
industry. Airline accidents unfortunately occur often
enough that it is difficult to determine which airlines are
doing a better job at safety than others. When accidents
do occur, it's impossible to know if one airline has more
accidents because it is more careless than others or because
it simply flies more than others. The statistics on this
page adjust for the differences in the number of trips an
airline flies each year to produce a standardized set of
numbers that allow you to objectively assess the safety record
of all airlines.
Why
are the statistics reported in a number "per million
takeoffs"?
Since some
airlines fly much more often than others, a raw count of
accidents, incidents, and near mid-air collisions would not
give an accurate picture of how safe one airline is compared
to another. Therefore all statistics are reported as a
number per 1,000,000 takeoffs. For
example, if an airline flew 5,000,000 takeoffs during the year
and had 10 accidents it would be reported as having 2
accidents per 1,000,000 takeoffs. Again, if another
airline flew only 500,000 takeoffs during the same year and
had the same number of accidents (10 accidents) they would be
reported as having 20 accidents per 1,000,000 takeoffs.
Clearly the second airline is less safe than the first (even
though they both had the same number of accidents during the
year).
Why
are there no statistics reported for foreign owned
airlines?
In order to
maintain a standardized set of statistics that allow a fair
comparison among airlines, the source data has to be
standardized. Most foreign countries do not make their
airline safety information available. Those that do will
have different definitions for "accidents" or
"incidents". These different definitions and methods
make it impossible to objectively compare safety records
between US airlines and foreign airlines.
Why
are some US airlines not in the tables?
In order to be
most effective, the statistics on this site are reported for
major airlines and large national airlines. Smaller
regional airlines are not included. In addition, among
the major and national airlines, there must be an unbroken
string of data available for a period of five years in order
to be included. This is necessary to provide for a
standardized comparison among all airlines covered.
Therefore airlines that have not been in business for at least
five years will not be found in these tables.
