On December 26, 2023, the new Mexicana finally took off. Before that, the date had been repeatedly postponed. The weather was not quite on its side at the time of the first flight, which was not fully booked, but at least the Boeing 737-800 was able to take off from Felipe Angeles International Airport. It is an aircraft that was previously used by the military. On government instructions, the military had to hand over some aircraft for operation by the new Mexicana, which is organizationally assigned to the armed forces anyway. In recent weeks, conversion, painting and re-registration have been carried out. The "old Mexicana" has not been in the air for some time due to insolvency. The restart is a prestige project of the government, which has had one or two teething problems. For example, it was not possible to organize enough aircraft in time, so the military had to step in. There is also an Embraer 145 on wet lease. However, the first flight could not be carried out to Tulum as originally planned, because the pilots had to divert to Merida due to poor visibility due to the weather. The "comeback flight" had the flight number 1788. The plane remained there until the weather improved. It then continued on to its actual destination. Local media claim that this was not the only reason for the stopover, because according to eyewitnesses, an unspecified liquid leaked from one of the two wings of the Boeing 737-800. During the unscheduled stop, technicians are said to have fixed this problem. Mexicana is to be positioned as a low-cost airline and undercut the rates of other carriers by an average of around 20 percent.
