About the Airbus A220-100
The aircraft began commercial service with SWISS in July 2016 as the CS100. The family became part of Airbus in 2018. Airbus gives the A220-100 a length of 35.0 meters (114 feet 9 inches) and the A220-300 a length of 38.7 meters. The shorter cabin is designed for routes where airlines need fewer seats.
Seating capacity
Airbus gives 100–120 seats as typical in two classes. Delta publishes an A220-100 layout with 109 seats, divided into 12 Delta First, 20 Delta Comfort and 77 Delta Main. These figures describe Delta’s published arrangement. Look up the operating airline’s seat map for the specific aircraft on your flight.
Cabin layout
Airbus describes a 2–3 layout around one aisle. In a full row with that layout, the pair has a window and an aisle seat. The block of three includes a middle seat. If you are booking two adjacent seats, the pair lets you share a block. The operating airline’s map shows where that arrangement applies and where the cabin changes, including premium rows or areas around exits.
How to recognize an Airbus A220-100
Look for the short single-aisle fuselage and one engine under each wing. The A220-300 is about 3.7 meters longer according to Airbus. Comparable side views make that difference easier to see. Since the two aircraft share their family design, check the registration and model record to confirm which version you are seeing.
Variants and related aircraft
The FAA lists the A220-100 and CS100 under BCS1. It lists the longer A220-300 and CS300 under BCS3. Delta uses 221 on its seat-map page for the A220-100. Use the full model name when matching the airline’s seat map to a radar filter.
