The Sukhoi Superjet 100 (Сухой Суперджет 100) or SSJ100 is a regional jet designed by Sukhoi, a division of the United Aircraft Corporation. With development starting in 2000, it made its maiden flight on 19 May 2008 and its first commercial flight on 21 April 2011 with Armavia.

The 46-49 t MTOW plane typically seats 87 to 98 passengers and is powered by two 77-79 kN PowerJet SaM146 turbofans developed by a joint venture between French Safran and Russian NPO Saturn. By May 2018, 127 were in service and by September the fleet had logged 300,000 revenue flights and 460,000 hours. The plane has recorded three hull loss accidents and 86 deaths.

The Airbus A350 XWB is a family of long-range, wide-body airliners developed by Airbus. The first A350 design proposed by Airbus in 2004, in response to the Boeing 787 Dreamliner, would have been a development of the A330 with composite wings and new engines. As market support was inadequate, in 2006 Airbus switched to a clean-sheet "XWB" (eXtra Wide Body) design, powered by Rolls-Royce Trent XWB turbofan engines. The prototype first flew on 14 June 2013 from Toulouse in France. Type certification from the European Aviation Safety Agency (EASA) was received in September 2014 and certification from the Federal Aviation Administration (FAA) two months later.

The A350 XWB is the first Airbus mostly made of carbon fibre reinforced polymer. It has a new fuselage designed around a nine-abreast economy cross-section, up from the eight-abreast A330/A340. It has a common type rating with the A330. The A350 XWB has two variants: the A350-900, typically flying 300 to 350 passengers over a 15,000 kilometres (8,100 nautical miles) range with a 280 tonnes (617,300 pounds) maximum take-off weight (MTOW), and the longer A350-1000, accommodating 350 to 410 seats over 16,112 km (8,700 nmi) due to a higher 319 t (703,200 lb) MTOW, supported by a six-wheel main landing gear up from four.

On 15 January 2015, the initial A350-900 entered service with its launch operator Qatar Airways, followed by the A350-1000 on 24 February 2018 with the same airline. As of December 2019, A350 XWB orders stand at 926 of which 347 have been delivered and 312 are in operation. The largest operator is the airliner's launch customer, Qatar Airways, with 48 A350 XWBs in its fleet. It succeeds the A340 and competes with the Boeing 777 and 787-10.

The Sukhoi Superjet 100 (Сухой Суперджет 100) or SSJ100 is a regional jet designed by Sukhoi, a division of the United Aircraft Corporation. Development started when Sukhoi saw a need for a regional jet that can have a larger range in the Russian market. Supported by the Russian government, Sukhoi designed an aircraft powered by two 77-79 kN PowerJet SaM146 turbofans developed by a joint venture between French Safran and Russian NPO Saturn. The prototype first flew on 19 May 2008 from Komsomolsk-on-Amur in Russia. Type certification from the Interstate Aviation Committee (IAC) was received in February 2011 and certification from the European Aviation Safety Agency (EASA) a year later.
