Thomson Airways will be entering a 90 day consultation period with members of the cabin crew this month.
A statement from the airline said: “This is as a result of our continuing drive to become more efficient which includes changes to the aircraft fleet. Boeing 737-800 aircraft requiring fewer cabin crew are replacing Boeing 757s when they come up for renewal.
“Thomson Airways is committed to mitigating the impact of these changes on cabin crew and is working in partnership with the relevant trade union to achieve this result.”
