How long can a plane go without refueling?

The record for the longest flight by a commercial airplane ever (though this was a test flight with no real passengers) was a Boeing 777-200LR's 11,664-nautical mile trek from London to Hong Kong, which lasted 22 hours and 42 minutes and saw two sunrises.

Thereof, how long a plane can fly?

A: This depends on the size of the plane, its efficiency, and how fast it's flying. A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!

How long can plane fly without engine?

Almost all commercial planes have a glide ratio between 15:1 and 20:1. At a cruising altitude of 40,000ft, a Boeing 777 can glide for about 210km without engines. A Boeing 747 can glide for about 170km or 20 minutes under favourable conditions.

How many years do planes last?

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.
