London - British Airways will retire its last remaining Boeing 767-300ERs by the end of this year.

Nearly 28 years after receiving its first 767, the British national carrier will end the operations of five 767-300ER in the fourth quarter of 2018. The last remaining units in service are the 767s registered as G-BNWX, G-BNWZ, G-BZHA, G -BZHC and G-BZHB.

The other two copies, the G-BNWA and G-BNWB, which were transferred to another IAG subsidiary Openskies have already been retired at the end of July.

A spokesman for British Airways interviewed by ATW said they did not know what would happen to these seven planes.

British Airways' 767-300ERs had a variety of cabin configurations ranging from 97 seats in Business Class and 147 in Economy (244 seats) to 24 in Business, 24 in Premium and 141 in Economy (259 seats) or 259 seats in Economy.

They are both operated on domestic routes in the UK and the international routes in Europe such as London - Amsterdam, Athens, Rome, Frankfurt, Stockholm, and Istanbul.

The next aircraft of the Oneworld alliance company to leave the fleet are the last three 777-200, which were replaced by 777-300ERs.

Recall that Boeing had removed from the table the possibility of re-engineering the aircraft for a new passenger version. Instead, Boeing aims to develop an entirely new aircraft for the middle of market (MoM) between single-aisle and twin-aisle. Boeing is in talks with the airline operators to form a concept for everyone's benefit.

But the program is currently under pressure by the arrival of Airbus A321LR. At Farnborough Air Show last month, Boeing announced that it postponed the decision for the program launch to 2019.

We want to be sure there is a firm demand for the type before launching the program,
said Boeing Chief Executive Dennis Muilenburg.

On the other hand, the freight version of the 767 is still available for sale.
