The A380 typically is on final approach at 140kts. To get there would involve a progressive climb [as fuel was used up, thus reducing the weight of the aircraft]. At maximum take-off weight from an airport at sea-level we would reach our initial cruising altitude in approximately 25 minutes.

The Airbus A380, the world's largest passenger aircraft, typically takes between 20 and 25 minutes to reach its initial cruising altitude, which is usually around 35,000 feet (10,600 meters). This climb rate is slightly slower than smaller, more nimble jets like the Boeing 737, which can reach cruise in about 15 minutes. The A380’s climb is a carefully managed phase designed to balance fuel efficiency with passenger comfort; because of its massive weight—up to 1.2 million pounds at takeoff—it often performs a "step climb." This means the aircraft will level off at a lower altitude for a period to burn off fuel and become lighter before climbing higher to more efficient, thinner air. Factors such as heavy payloads, air temperature, and air traffic control restrictions can further influence the total time it takes for this giant of the skies to level out.
