Asiana Airlines A350-900

The staggered layout gives every seat direct aisle access, so nobody climbs over you, and the seat lies flat for sleeping on the long routes this aircraft flies. Add the quieter, more humid A350 cabin and it is Asiana's most comfortable long-haul Business product, which is why the aircraft type is worth checking when you book.

The bulkhead rows behind a cabin divider give the most legroom, though they lose under-seat stowage. A window or aisle seat avoids the middle of the three-across centre block, and the front of Economy boards and clears faster than the rear rows by the galleys and lavatories.

Yes. In the staggered cabin the window-aligned seats that sit further from the aisle are the most private, and they still keep direct aisle access. Toward the rear of the cabin you also sit further from galley traffic, which suits anyone hoping to sleep.
