Do all life insurance policies pay a death benefit due to a commercial airline accident?

If death occurs while flying as a passenger on a commercial airline, due to a crash, that passenger who has an active life insurance policy is considered insured, and his beneficiary will receive the face amount of the policy as a death benefit.

If the policy includes an active accidental death rider, not only does the policy pay the face amount death benefit, but it is doubled.

Death from a crash by a commercial airline is always considered accidental.
