The A350 XWB has been designed with passenger well-being at the forefront, offering the quietest, most comfortable cabin in this aircraft size category. With a cabin cross-section of 220 inches/5.58 meters from armrest to armrest, the A350 XWB provides wider aisles and the widest seats in the industry. Compared to its nearest competitor, the A350 XWB cabin is 5 inches/12.7cm wider, offering superior levels of spaciousness for passengers.

Seating in economy, for example, can be either eight abreast for high comfort or nine abreast for extra high efficiency. The modular cabin features of the A350 XWB Family allow overnight reconfiguration, enabling airlines to easily adapt to specific seasonal needs and changing markets. This capability further enhances operating flexibility.
Thanks to leading edge cabin design, passengers will also benefit from more headroom, wider panoramic windows, and larger overhead storage space.

The use of latest technologies results in enhanced air quality and cabin environment regulation. Improved purity of cabin air is provided by gaseous filters and Ozone/Volatile Organic Compound (VOC) converters. More precise temperature control zones, draft free air circulation, controlled cabin humidity of up to 16 per cent during flight cruise and a typical cabin altitude at or below 6,000 ft, further enhance passenger well-being.
