[5][6][7][8] As of December 2020, the Interjet CFO announced the suspension of all operations and from the IATA for its non-payment of debt, primarily fuel costs.

On July 21, 2011, Interjet made its first flight in North America (and the fourth worldwide) using biofuel,[16] on the Mexico City – Tuxtla Gutiérrez route, with an Airbus A320-200, registration XA-ECO.

In 2012 the airline committed to purchase the Sukhoi Superjet 100 (SSJ100), which sold for about a half the price of a comparable Bombardier Aerospace or Embraer aircraft.

Interjet CEO Jose Luis Garza said it was the best choice for hot and high Mexico City, a bold bet on Russia's first major airplane since the Soviet Union collapsed.

[21] In September 2018, Interjet was reported to be considering replacing its SSJ100s with Airbus A320neos, to make better use of its slots, with the SSJ technical problems a possible factor.

[29] The shaky financial situation continued through 2020, with Interjet having to cancel all flights for the 1st and 2 November after failing to pay for fuel.

[34][35][36][37] The Procuraduría Federal del Consumidor (PROFECO) advised passengers against booking flights on and flying with the airline, and provided compensation for the affected customers.

[42] According to a report, the airline's unpaid taxes, bills, fees, and cancellations resulted in an embargo placed on the properties of the father of former president Miguel Alemán Magnani by the SAT, legal action by customers, and Chicago officials.

Sources also say that 50 unpaid workers who have been laid off since March have filed lawsuits against the airline, stating it owes them $11 million pesos.

[47] In an interview with a Mexican news outlet, tax authority director Raquel Buenrostro said that the airline is already bankrupt, stating that "Interjet has no cash flow..."[citation needed] The airline's general director, Carlos Rello, stated that it depended on the SAT for tax payments with medical supplies in order to cover the debt and attract capital from investors.

[10][63][57] Mexico's president Andrés Manuel López Obrador ruled out the possibility of a bailout from the government, stating that it "cannot be rescuing companies, [...which] was done previously and it was abused a lot."

[66] In March 2021, Interjet has officially requested to file for commercial bankruptcy by the end of the month in order to receive investment funds and resources.

[citation needed] By April 2023, the federal court decided to liquidate the company and order the auction of its properties meaning Interjet will no longer fly again.

Interjet has also become a popular choice for surfers traveling to Mexico because of its baggage policy of not charging extra fees for those passengers transporting a surfboard on domestic flights.

On June 21 that year the airline began flights to its second Central America destination; to San José de Costa Rica from Mexico City International Airport.

On May 15, 2017, Interjet announced its first routes to Canada, with thrice weekly flights to Montréal–Pierre Elliott Trudeau International Airport from Mexico City and Cancún with Airbus A320 aircraft.

[76] On December 15, 2018, Interjet began service to Monseñor Óscar Arnulfo Romero International Airport in San Salvador from Mexico City.

[77] On June 5, 2019, Interjet began service to José María Córdova International Airport in Medellín, Colombia from Mexico City and Cancún.

[78] On October 1, 2019, Interjet began service to José Joaquín de Olmedo International Airport in Guayaquil, Ecuador from Mexico City and Cancún.

[79] On October 28, 2019, Interjet began service to Mariscal Sucre International Airport in Quito, Ecuador from Mexico City.
