[3] CityJet ended its own-brand scheduled services in 2018 and is now a major provider of wet leasing to European airlines.

[7] In June 1995, Virgin Cityjet debuted with flights between Dublin and Brussels, competing with Sabena and Aer Lingus initially.

[7] In 1996, the airline terminated its franchise agreement with Virgin Atlantic on short notice and decided to continue operations using its own CityJet name from the end of July that year.

Under the new structure, Cityjet retained its own scheduled services while also becoming Air France's principal European subcontract airline.

[10] The French national airline was allowed to outsource operations of aircraft with less than 100 seats to regional partners and subsidiaries under its contracts with Air France' labour unions; overall savings to Air France by outsourcing regional operations to the Irish subsidiary were estimated at around 40 percent.

[16] In December 2013 Air France announced it would sell CityJet, including VLM Airlines, to German investor Intro Aviation.

[21]On 28 June 2016, CityJet inaugurated its Sukhoi Superjet 100 revenue services with its first scheduled flight from Cork to Nantes.

[27] On 5 April 2017, it was announced that KLM Cityhopper would wet lease two Avro RJ85s from CityJet to operate four additional Amsterdam–London City services per weekday over the Summer 2017 season, starting 15 May 2017.

In late October 2017, CityJet cancelled most of its remaining routes from London City Airport, leaving Dublin as its only scheduled destination from there after operating a much larger network in previous years.

[30] In late August 2018, CityJet announced they would cease operating scheduled services under their own brand, effective from 27 October 2018, but continue business as an ACMI leasing provider.

At the end of October 2018, CityJet commenced a wet lease agreement with Aer Lingus, operating two Avro RJ85 aircraft primarily on the Dublin to London City route.

In May 2021 CityJet handed its 75% share of Air Antwerp over to co-owner KLM but the airline ceased operations in June 2021.

In March 2023, CityJet took delivery of the first of five Bombardier CRJ1000 100-seat regional jets [38] to supplement its fleet of 21 CRJ900s, with the first two flying on a wet lease contract with Lufthansa.

[39] A new wet lease contract with Brussels Airlines commenced in March 2023 for the upcoming 2023 summer season using two CRJ900 jets.
