Beginning in November 2023, Corendon Airlines has set aside 93 regular seats and nine extra legroom seats in an adults-only section of the aircraft of the company’s Airbus A350 jets, which has a total of 432 seats. 

The section was located at the front of the plane and was blocked off from the rest of the aircraft with a wall and a curtain to eliminate the noise of any children on board. 

This is only a section of the airplane. This question will resolve YES if a whole plane is adult only, which will be seats reserved for people 18 years or older. If this doesn't happen by the end of 2030 the question will resolve NO. Only commercial airlines count.
