777-200. According to data from ch-aviation.com, the oldest active example of the Boeing 777-200, and indeed the most senior of any remaining triple-seven worldwide, is a United Airlines jet that bears the registration N774UA.

The Boeing 777 is the best-selling long-haul carrier in the history of aviation. It has an exceptional life-span of 30 years, but what's the secret behind this record-breaking longevity? In this film, a 777 is taken apart, inspected, and entirely refurbished.
The 777 is produced in two fuselage lengths. The original 777-200 model first entered service in 1995, followed by the extended-range 777-200ER in 1997. The stretched 777-300, which is 33.3 ft (10.1 m) longer, began service in 1998.
Current prices for a used 777 range from as little as $3.5 million to $13 million for airplanes in airline configuration. (You can still pay $200 million or more for one that's already finished to royalty standards.)
Then I flew on the World's oldest active B777, N774UA, a original Boeing 777-200 A model from Chicago to Denver. The plane was 26.0 years old, line number 002 from Boeing.
Aircraft age is not a safety factor. However, if the aircraft is older and hasn't been refurbished properly, it may cause flyers some inconvenience such as overheating, faulty air conditioning, or faulty plumbing in the lavatory.
The trijet 777 was later dropped, following marketing studies that favored the 757 and 767 variants. Boeing was left with a size and range gap in its product line between the 767-300ER and the 747-400.
The Boeing 777-200LR holds the world record for the longest non-stop flight without refueling with a flight distance of 11,664 nautical miles (21,601.7 km). The 777-300ER, which is the most popular variant, has a range of 14,490 kilometers (7,825 nautical miles).
“The Boeing 777's unique combination of superior range, outstanding fuel efficiency and passenger-preferred comfort has created long-range success for carriers around the world. And the 777-300ER now gives operators a perfect opportunity to extend that success.
On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.
Conclusion. Whether you board a brand-spanking-new state-of-the-art airliner or a 40-year-old turboprop, rest assured that strict regulations ensure that the aircraft will be serviceable and safe!
What makes the plane so expensive? The 777-300ER can carry 365 passengers compared with the 787-9's capacity of 280. The GE engines on the 777 model develop 62% more thrust than the 787's two engines. The plane is also longer than the Dreamliner, has a greater wingspan and a greater wing area, and is taller.
