Philippines’ national carrier Philippine Airlines has finally permanently phased out its entire Boeing 747 fleet. The Boeing 747 aircraft conducted its last flight between San Francisco International Airport and Manila’s Ninoy Aquino International Airport on September 1, 2014.

The airline’s Boeing 747-400 aircraft had been into operations for the last 35 years. It continued to be the airline’s flagship aircraft until retirement. Philippine Airlines said that it has permanently phased out the Boeing 747 fleet and replaced it with more fuel efficient Boeing 777.

According to Philippine Airlines, the Boeing 747 aircraft was the first to enter service in December 1979. It was during this period that the airline received the delivery of its first Boeing 747-200 aircraft, which was considered to be the most modern and largest aircraft in its fleet. This allowed the airline to launch new products and services. The new product included the first ever lie-flat beds known as “Skybed” for First Class passengers.

Philippine Airlines also became the first airline to operate nonstop flights to the United States and Europe across the Pacific using its Boeing 747 aircraft during the 1980s. The airline later on received its Boeing 747-400 aircraft. It was the first model of its kind to join the airline’s fleet in November 1993. By the year 2003, the total number of Boeing 747 aircrafts in the airline’s fleet reached up to five.

Over a period of 35 years the airline used its Boeing 747 fleet to primarily operate long-haul high-density routes spanning North America, Middle East, Europe and Australia. The Boeing 747 fleet was also occasionally used to serve some domestic and regional routes as well.
