Interjet

Foundation

Interjet started operations on December 1, 2005, with one Airbus A320 aircraft. The airline placed an order for 25 new A320s to replace the second-hand ones, which was increased by another ten aircraft on January 10, 2010.

Initially, most Interjet flights were to and from its hub in Toluca International Airport, which it branded "Mexico City - Toluca Airport" and which was widely seen at the time as a viable base for low-cost carrier service for the Mexico City market. By 2008 it had 14 routes from Toluca and three between other cities. After the demise of Mexico City-based competitor Aero California in August 2008, Interjet took over the vacant slots and established flight services to Mexico City International Airport.

Expansion and new fleet

On July 21, 2011, Interjet made its first flight in North America (and the fourth worldwide) using biofuel, 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.

In 2014, the airline described itself as the "JetBlue of Mexico". However, by 2018, the airline had moved to a hybrid model, with low ticket prices and high cost "extras" such as extra legroom, free legroom, but a more generous luggage policy associated with traditional carriers.

On March 2, 2015, Interjet confirmed ten SSJ100 options valued at $350 million.

In mid-January 2018, Bloomberg reported that four out of 22 of Interjet's SSJ100s were cannibalized for parts to keep others running, after having been grounded for at least five months because of SaM146 maintenance delays. This was later refuted by Interjet; a Russian magazine reported that one grounded SSJ100 was going to be back in service by January 19, and the remaining three by March.

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. This would have left CityJet as the only remaining Western customer. On September 12, Interjet denied the report.

Interjet claimed its capital cost for ten Superjets is equivalent to the pre-delivery payment for one Airbus A320. The pre-delivery payment amounts to 15-30 percent of an aircraft list price. The list price of an A320 was $88.3M in 2012.

By January 2020, Interjet confirmed that it was planning to phase out its SSJ100 fleet, and by November of that year was operating only 4 of its 22 SSJ100 models. After the carrier quit flying in December 2020 and entered bankruptcy in April 2021, its plan to try to resume operating was to attempt to return its SSJ100s to Sukhoi to cancel its debt, and fly instead with 10 Airbus A320 aircraft.

Financial debt, COVID-19, new CEO, and cancellations

With the suspension of many of its operations because of the COVID-19 pandemic, there were reports of financial problems. The airline has suspended all international operations following the pandemic. The shaky financial situation continued through 2020, with Interjet having to cancel all flights for 1 and 2 November after failing to pay for fuel. Even before the pandemic, the airline had been in financial trouble since 2013, citing unpaid taxes. The airline temporarily reduced the salaries of its workers by 50% to further cut debt. From November 30 to December 3, the airline again cancelled flights as it had still failed to pay for fuel despite its commitment to provide reimbursement by December 8, 2020. The airline didn't notify customers and staff, causing many to be stranded. In Cancún International Airport, following the cancellations, many paid up to 5,000 pesos for different airlines. The Procuraduría Federal del Consumidor (PROFECO) advised passengers against booking flights on and flying with the airline, and provided compensation for the affected customers. The airline once again cancelled all flights from December 11, 2020, until the end of January 2021, after still being unable to pay for fuel. As a result, IATA once again suspended the airline, but now entirely, and from its Billing and Settlement Plan, and advised travel agencies and GDS to suspend all ticket sales for the airline. In April, IATA dismissed the airline from the Clearing House. Despite the suspensions, the airline still remains a member of the IATA. The airline postponed its relaunch dates of December 17, December 31, and then January 11, 2021. Amidst the financial issues, Interjet's head Miguel Alemán Magnani resigned. In November 2020, Alejandro del Valle was appointed the airline's new CEO and later became chairman of the board of directors.

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.
