Doha-based flag carrier Qatar Airways has spent the past decade redefining what business class can be, and its signature Qsuite is the ultimate benchmark for overall quality. A product that offers what is consistently ranked among the world’s best business-class cabins, the Qsuite pairs complete privacy (brought along by a sliding door) and clever storage, all hallmarks of modern long-haul comfort. The cabin features a wide, fully lie-flat bed, plush bedding, and restaurant-style dining on demand. What ultimately makes Qsuite one of the best cabins in the sky is its incredible flexibility. Solo travelers can settle into a cocooned window suite, while couples can convert center seats into a comfortable double bed. Families and colleagues can form a quad of seats, which opens partitions to create a shared living and dining space, all while in the sky.
