Oman Air (WY, Muscat) has retired all four of its E175s, more than two years after they were withdrawn from use.

A4O-EB (msn 17000324) was ferried from Muscat via Sharm el Sheikh to Katowice Pyrzowice on March 29, 2022, followed by A4O-EA (msn 17000323), A4O-EC (msn 17000349), and A4O-ED (msn 17000354) on April 14, 2022. They have since been deregistered from Oman and re-registered in the Isle of Man as M-ABPS, M-ABPR, M-ABPW, and M-ABPX, respectively. They are owned by an Irish SPV, Likoma Propco 1/2.

All four Embraer regional jets were retired from commercial service as of March 21, 2020, as the COVID-19 pandemic began. They have since only operated sporadic test flights in Oman.

The E175s were the Omani carrier's only regional aircraft. The airline was also the last commercial operator of any non-executive regional jets in the Gulf region. The ch-aviation fleets module shows that currently, Oman Air's smallest aircraft type is the B737-800.
