Could pod seats be the future of air travel? He denied that the seats would be difficult to get in and out of, comparing it to hopping into a large 4x4 vehicle, but admitted that they would not suit passengers with mobility issues. Once inside, passengers would be able to sit upright or lie flat. The designer also suggested airlines should adopt different way of grouping passengers on board an aircraft, in zones according to passenger needs rather than simply Economy, Business and First classes. Such an arrangement would allow for a wider variety of passengers to have a more comfortable flight, he said. "You would have an A-Zone, a B-Zone, maybe down to five or six different zones in an aircraft," he said. It's a seat for single people. It is a private space [The Air Lair] would be a restricted zone and it's restricted because the nature of the seating is different and therefore the activity is different. You would only want to be in an Air Lair pod if you wanted to have no contact with other passengers. It is a private space. At this stage, however, there are no concrete plans to introduce Air Lair pods into any aircraft. Which cabin design would you like to see in the future?
