The holiday airline Chair Airlines has been using a Boeing 21-2021 operated by Enter Air since July 737, 800 as part of a wet lease contract. The Polish company holds 49 percent of the Swiss aviation company.

Since the ACMI order is long-term, the SP-ESE received a kind of “hybrid livery”. According to CH-Aviation.com, the Enter Air logo has been replaced by that of Chair Airlines. Otherwise, this Boeing 737-800 should also wear the color scheme of the Polish supplier.

Chair Airlines emerged from the Swiss branch of Germania. In the course of the bankruptcy of the German group, the carrier was taken over by the owners of the travel agency Air Prishtina. A short time later, Enter Air got involved with a 49 percent minority stake. The fleet currently consists of two Airbus A319s, with another aircraft of the same construction being so badly damaged during maintenance work carried out by an external company in the previous year that it is a total economic loss.
