In 1958 the first transatlantic flight by a jet aircraft began a completely new era of competition for the Cunard Queens. With a London–New York travel time of just 7–8 hours now possible with the new aircraft, demand for a sea crossing of the ocean fell away markedly. On some voyages, winters especially, "Queen Mary" sailed into harbour with more crew than passengers, though both she and "Queen Elizabeth" still averaged over 1,000 passengers per crossing into the middle 1960s. By 1965, the entire Cunard fleet was operating at a loss.
