Scandinavian Airlines (SAS) is extremely pleased to announce its first of eight new Airbus A350 aircraft will officially enter service next January. Long-haul passengers shuttling between Copenhagen and Chicago will be the first ones to experience the Star Alliance member airline's new aircraft and all that it has to offer beginning January 28, 2020.

That said, Scandinavian Airlines has revealed that it plans to use the fuel-efficient long-haul A350 aircraft on six other routes in 2020. These long-haul routes include those linking Copenhagen to New York, San Francisco, Tokyo, Hong Kong, Beijing and Shanghai. The carrier is expecting to take delivery of its first A350 plane in late 2019.

Scandinavian Airlines' A350 aircraft offers a total of 300 seats, including 40 SAS Business, 32 SAS Plus and 228 SAS Go seats.

The SAS Business seat converts to offer Business Class passengers a fully flat bed. Passengers flying in this cabin will also get to enjoy gourmet meals and proper espresso onboard, check in two large bags (up to 71 lbs each), take two carry-ons (up to 18 lbs each) and a small handbag or laptop bag onboard. In addition to going through security with SAS Fast Track, SAS Business passengers get to enjoy access to SAS Lounges, free high-speed internet onboard and more.

SAS Plus passengers enjoy more legroom, wider seats as well as adjustable headrests and footrests on long-haul flights. Besides the ability to check in two bags weighing up to 51 lbs each and bring two carry-ons (up to 18 lbs each) and a small handbag or laptop bag onboard, SAS Plus passengers also have access to SAS Lounges, SAS Fast Track, complimentary high-speed internet onboard and more.

The SAS Go cabin is essentially like your standard Economy Class cabin. While SAS Go seats are often priced competitively, all passengers traveling in this cabin can enjoy free coffee and tea during flight. There are free digital magazines and newspapers for their enjoyment as well - these are available from 22 hours before departure in the SAS App.

SAS Go Smart passengers on long-haul routes can enjoy food and non-alcoholic beverages, check in a bag weighing up to 51 lbs, bring a carry-on weighing up to 18 lbs and a small handbag or laptop bag, choose their seats for free when they check in online or through the SAS App 22 hours before departure and more.

SAS Go Light (i.e. Basic Economy) passengers will not be able to check in any bag, though. Passengers who opt for SAS Go Light can bring a carry-on weighing up to 18 lbs and a small handbag or laptop bag onboard and pick their seat at no additional charge when they check in online or through the SAS App 22 hours before departure. Meals are not included for those who opt to travel on this ticket type.
