(Web Desk) - The concept design includes three massive floors, six huge engines, and a panoramic viewing lounge - with a state-of-the-art theatre and casino in the nose of the plane.
Dubbed the "Progress Eagle", the enormous flying hotel-like design features an incredible wingspan of 315ft and is some 263ft long.
The plane is a brainchild of leading Spanish designer Oscar Vinals and if created, it will edge out the massive Airbus A380-800 which comes in at 240ft and the 230ft Boeing 747.
An upgraded version of the plane called the "One Flight" would feature cabins rather than banks of airline seats.
While the standard aircraft will fit 800 passengers, the special edition will only be able to fly 300 passengers in one trip.
However, One Flight is expected to offer passengers the best flying experience - with access to lavish onboard facilities including a restaurant, a spa, a cinema, shops and a casino.
The cockpit of the flight has been designed to be on the second floor, allowing the fuselage to extend out and create an incredible viewing deck.
Flying at 40,000ft, passengers will be able to enjoy surreal, almost 180-degree panoramic views of the sky, thanks to creative bulbous design.
To offer passengers a luxury cruising experience, the seats would be scattered throughout the three decks - with a tourist class, business class, and pilot class on board.
However, one of the most striking features of the futurist jet would be its unconventional fuel source to power six massive engines.
The design of the plane aims to ditch fossil fuels in favour of using hydrogen fuel cells.
This will help the aircraft become more "self-sufficient" and cut down on energy drastically as compared to modern aircraft.
The roof and wings would be covered in solar panels, along with an onboard wind turbine to help it gather the energy it needs to keep its batteries topped up.
The aircraft could even stay airborne almost indefinitely, using an ambitious power supply based on solar collecting satellites.
While the impressive design of the Progress Eagle looks tempting, its creator Vinals believes only half the technology is available today to turn the dream aircraft into reality.
