In Europe, most network carriers have long since removed aircraft with 50 or fewer seats from their fleets. In the USA, there are still many aircraft in use, but American Airlines is now starting a trend: the small aircraft are to be retired by 2030. The Oneworld member does not formally operate a single aircraft with 50 or fewer seats. These are operated by subsidiaries and/or subcontractors. American Airlines has now decided that these aircraft are to be replaced by larger models by 2030. Scope clauses negotiated with unions mean that the Embraer 175 will play a special role. The Brazilian aircraft manufacturer has not been able to sell an E175 outside the United States for some time. In the USA, it was only recently able to land a major order again. Background: This model can be operated by subsidiaries or formally independent regional airlines, usually on a wet lease basis for large carriers. However, it depends on the scope clause with the relevant union. The contracts are not uniform. American Airlines is of the opinion that the 50-seaters have become disproportionately expensive to operate. European providers came to this conclusion many years ago, as the Lufthansa Group, for example, has long since parted ways with smaller jets and turboprops in this size class. For example, American Airlines currently has many Embraer ERJ-145s flying, which will be affected by the planned phase-out. The group's own Envoy Air already removed this model last year. However, it was not until XNUMX that the company decided to phase out the aircraft.
