Silverjet was a British all-business class airline headquartered at London Luton Airport, Luton, Bedfordshire, England, that, prior to the suspension of operations on 30 May 2008, operated services to Newark Liberty International Airport and Dubai International Airport. A proposed rescue package fell through on 13 June when staff were laid off and it was announced that the airline's assets would be sold.

Silverjet Aviation Limited was created in 2004 by Lawrence Hunt. Prior to launch, the airline secured sufficient funding to begin trading on the AIM, a market operated by the , and joined the AIM on 12 May 2006. The airline secured two Boeing 767-200 aircraft in August 2006 that were previously operated by Thomsonfly. These were delivered in March 2007 and October 2007 and were Silverjet's launch aircraft. With the acquisition of British Charter Flyjet in October 2006, Silverjet took ownership of their two Boeing 757 and one Boeing 767 aircraft. This also provided Silverjet with Flyjet’s Air Operator’s Certificate, Operating Licence and a worldwide Route Licence.

Silverjet’s website, designed by Prospect, began taking passengers' bookings for flights on 12 October 2006, for a standard fare of £999. Silverjet's first scheduled flight between London Luton and Newark began on 25 January 2007, and a second daily service on this route was launched on 23 September 2007. Services from London Luton to Dubai International commenced on 18 November 2007, and the airline planned to launch other long-haul destinations in the future, but this expansion was halted because of Silverjet's financial troubles.

At the beginning of May 2008, Silverjet stated that they had arranged an $8.4 million loan facility from Viceroy Holdings, a Middle Eastern investor. However, the airline was unable to draw down $5 million that it needed urgently, and, on 23 May 2008, trading of Silverjet's shares was suspended on the AIM. Later, on 30 May 2008, a statement was released from Silverjet's CEO that stated Silverjet would cease operations and suspend all flights with immediate effect due to failing to secure funding. The last operating flight, SLR254, arrived at London Luton Airport from Dubai at 15:00GMT on the day of the announcement.
