Emirates Airline has taken the wraps off a new first class suite on board its latest aircraft that features virtual windows.
Instead of being able to see directly outside, passengers view images projected in from outside the aircraft using fibre-optic cameras.
But it seems not everyone would be happy with boarding an aircraft without windows, including those who like to look out of real windows, and those who already become anxious with the claustrophobic nature of aircraft cabins.
Undaunted, Emirates said the new windowless cabins pave the way for removing all windows from future planes, making them lighter, faster and more fuel-efficient.
Emirates president Sir Tim Clark said the virtual window images were "so good, it's better than with the natural eye".
The virtual windows can be found in the first class cabin of Emirates' newest Boeing 777-300ER aircraft.
Sir Tim told the BBC that the ultimate aim was to have planes with no windows at all.
"Imagine now a fuselage as you're boarding with no windows, but when you get inside, there are windows," he said.
