Butterfly
Butterfly is a flexible aircraft seating system that allows transformation between premium economy seats and business class flatbed suites. Each Butterfly suite contains two reclining seats staggered relative to each other, and both seats together are sold as premium economy. Cabin crew can flip the window seat over to form a side couch, creating a business class suite for one passenger. Flipping the aisle seat as well creates a large flat surface for sleeping. The system lets operators adjust the cabin to changing demand and use floor space efficiently.
