for vice presidential candidate Sarah Palin. On 14 October 2017, an Airlink E190-100IGW with 78 passengers aboard inaugurated the first scheduled commercial airline service in history to Saint Helena in the South Atlantic Ocean, arriving at Saint Helena Airport after a flight of about six hours from Johannesburg, South Africa, with a stop at Windhoek, Namibia. The flight began a once-per-week scheduled service by Airlink between Johannesburg and Saint Helena using E190 aircraft. The inaugural flight was only the second commercial flight to Saint Helena in the island's history, and the first since a chartered Airlink Avro RJ85 landed at Saint Helena Airport on 3 May 2017. Variants E170 The E170 is the smallest aircraft in the E-Jet family and was the first to enter revenue service in March 2004. As of 2017, the E170 is out of production. The E170 typically seats around 72 passengers in a typical single class configuration, 66 in a dual class configuration, and up to 78 in a high density configuration. The E170 directly competed with the Bombardier CRJ700 and loosely with the turboprop Bombardier Q400. The jet is powered with General Electric CF34-8E engines of 14,200 pounds (62.28 kN) thrust each. E175 The E175 is a slightly stretched version of the E170 and first entered revenue service with launch customer Air Canada in July 2005. The E175 typically seats around 78 passengers in a typical single class configuration, 76 in a dual-class configuration, and up to 88 in a high-density configuration. Like the E170, It is powered with General Electric CF34-8E engines of 14,200 pounds (62.28 kN) of thrust each. It competed with the Bombardier CRJ900 in the market segment previously occupied by the earlier BAe 146 and Fokker 70. , it is the only aircraft currently produced in this market segment. The E175 was initially equipped with the same style of winglets as the rest of the E-Jet family. This was changed starting in 2014 to wider, angled winglets as part of an efficiency improvement package. The angled winglets increase the wingspan from 26.00m (85 ft 4 in) to 28.65m (93 ft 11 in). This winglet change was only made available to the E175 version. In late 2017, Embraer announced the E175SC (special configuration), limited to 70 seats like the E170 to take advantage of the E175 performance improvements, but still comply with US airline scope clauses limiting operators to 70 seats.
