With bmi Regional, bmibaby transferred to International Airlines Group ownership on completion of the purchase from Lufthansa.
IAG has consistently said that bmibaby and bmi Regional are not part of its long-term plans.
Progress has been made with a potential buyer for bmi Regional, but so far this has not been possible for bmibaby, despite attempts over many months by both Lufthansa and IAG.
bmibaby has therefore started consultation to look at future options including, subject to that consultation, a proposal to close in September this year.
