Fleet

Throughout its existence, SilkAir operated the following aircraft:


Fleet development

SilkAir began operations with one leased McDonnell Douglas MD-87 aircraft in 1989, before investing in its own fleet of six Boeing 737-300s, the first of which began operations in 1990. It operated two Airbus A310-200s for a brief period from 1993 to 1995 before they were transferred to Singapore Airlines, and two

arrived on 18 September 1998, and retired all Boeing aircraft a year later. Soon after its first A320 was delivered, SilkAir took delivery of its first A319-100 aircraft on 3 September 1999. The A319 was utilised on certain routes within Southeast Asia, and to some cities in India, while the larger A320 was used on most of the airline's major routes. On 20 December 2006, SilkAir signed an agreement to purchase 11 Airbus A320-200 aircraft with nine more on option. These aircraft were delivered between 2009–2012. On 3 August 2012, SilkAir had signed a

In-flight entertainment

SilkAir offered a selection of newspapers and magazine titles on board and screened a series of short features on its 11-inch overhead dropdown screens. The ''Silkwinds'' inflight magazine was complimentary for all passengers. In-seat audio and power supply were available exclusively on its Boeing aircraft. 2014 saw the launch of SilkAir Studio as a complimentary wireless streaming service for its passengers. It was first available on its Boeing 737-800 aircraft before being progressively rolled out to its Airbus fleet. This system complemented the existing overhead systems. SilkAir Studio was introduced in 2014 where passengers were able to stream blockbuster hits, short features, and music, to their personal laptops and handheld devices via Wi-Fi. This system complemented the existing overhead systems. Passengers in Business Class on flights more than two hours were offered a tablet. In May 2017, the service was enhanced and upgraded to offer more than 150 international blockbuster movies and TV sitcom shows available on SilkAir Studio. For Apple users, the SilkAir Studio app had to be downloaded prior to flight in order to enjoy the in-flight entertainment.

. The jury under the Superior Court in Los Angeles in 2004, which was not allowed to hear or consider the NTSB conclusions, decided that the crash was caused by a prominent issue inherent in other 737 crashes: a defective servo valve inside the Power Control Unit (PCU) which controls the aircraft's rudder, causing a rudder hard-over and a subsequent uncontrollable crash. The manufacturer of the aircraft's rudder controls and the families later reached an out of court settlement. It is the only fatal hull loss for SilkAir in its history.
