The United States notice of denunciation of the Warsaw Convention for the Unification of Certain Rules relating to International Carriage by Air, opened for signature at Warsaw on October 12, 1929, even though now withdrawn, marks the end of an era in the development of private international air law. The notice of denunciation was communicated to the Polish government, depositary of the Convention, on November 15, 1965, because, according to the United States of America, the present limit of liability — which amounts approximately to $8,300 U.S. — applicable in the case of death of, or injury to, a passenger in international carriage was considered to be no longer adequate to protect United States citizens of practically all economic levels who in ever-increasing numbers are making use of international air transport. On May 13, 1966, just two days before the denunciation was to take effect, the United States dramatically withdrew its notice after a series of eleventh-hour discussions and consultations culminating in an agreement by thirty-four airlines to accept a limit of liability of $75,000 U.S. per passenger and, with the exception of three American airlines, to accept also the absolute liability of the air carrier. The notice of denunciation of what has often been described as one of the most widely accepted conventions of its kind sent a wave of uneasiness through the world of international civil aviation. As a result of that notice, the Warsaw system came under searching examination and, in view of the agreement mentioned above, will, no doubt, be substantially modified when, in due course, a diplomatic conference is convened to amend the Convention.
