The rise of oil prices and collapse in consumer travel damaged airlines and many of Gate Gourmet's main customers went bankrupt or narrowly avoided bankruptcy.

[5] On September 27, 2007, Gate Gourmet acquired a UK-based group operating under the Fernley and International Aviation Services (IAS) brands.

The companies operate primarily in the UK, including at London's Heathrow, Gatwick, Stansted and Luton airports, as well as Manchester, Dublin, Cork, Shannon, Liverpool, East Midlands, Biggin Hill and Glasgow.

[12] In April 2016, Chinese conglomerate HNA Group offered to buy Gategroup for 1.4 billion Swiss francs.

[13] In the beginning of July 2016, HNA Group declared they had bought 63.6 percent of the voting rights and shares in Gategroup.

[14] By October 2016, HNA Group had acquired 96.1 percent of the voting rights and applied for a delisting of the remaining shares in Gategroup.

As a result, RRJ Capital became the sole shareholder and Temasek was invested in gategroup through a mandatory exchangeable bond.

[22] On December 2, 2020, Gategroup announced the completion of the acquisition of LSG Group's European business from Deutsche Lufthansa AG.

[26] The American head of Gate Gourmet at the time, Dave Siegel, blamed the industrial action on "the most irrational, irresponsible group" he had ever seen in organised labour.

[28] The company subsequently offered a redundancy package of more than twice the statutory minimum in an effort to resolve the labour difficulties, secure a new deal with British Airways, and avoid insolvency.

[28] In December 2018, a survey by the union of drivers for Gate Gourmet flagged concerns about the catering vehicles used to service planes.

[32] After the outbreak, the U.S. Food and Drug Administration (FDA) inspected Gate Gourmet's Honolulu facility and determined that there were substantial problems.

[33] On July 16, 2012, sewing needles were discovered in four different turkey sandwiches on separate Delta Air Lines flights.

[34] In response to the incident, Delta advised all of their flights leaving Schiphol Airport to stop serving the sandwiches, and an FBI investigation was launched to determine the cause.
