Around 400 employees of Monarch Airlines based in Birmingham will lose their jobs after the firm served staff with redundancy notices.
The joint administrators of Monarch Airlines Limited and Monarch Travel Group have confirmed that 1,858 employees have been made redundant.
Of these, 1,760 were employees of Monarch Airlines, while 98 were employed by Monarch Travel Group.
The airline, founded in 1968, flies to over 40 destinations from five UK bases: London Gatwick, Birmingham, Manchester, Leeds-Bradford and Luton.
Between them the companies employed approximately 2100 people.
The remainder have been retained by the joint administrators to assist them in the administration process and to help collate critical information to assist the Civil Aviation Authority with the repatriation of customers who are currently overseas.
The Group’s engineering operation, Monarch Aircraft Engineering Limited, is not in administration and continues to trade normally.
