UK budget carrier BMI Baby to cut jobs and routes

* Up to 158 pilot, crew, management jobs to go

* Says will reduce routes and fleet size

LONDON, Nov 4 (Reuters) - Low-cost airline BMI Baby, part of the BMI Group, on Wednesday said it would to cut up to 158 jobs and reduce the number of routes it flies due to the ongoing impact of the economic downturn.

The airline, owned by German carrier Lufthansa AG (LHAG.DE), said 54 pilot and 82 cabin crew positions at Britain's Birmingham, Manchester and Cardiff airports were "at risk of redundancy", as were an additional 22 management and support positions at its head office and at other airport bases.

BMI Baby also said it would reduce its fleet size by five aircraft in 2010 from the current 17 due to "the worst economic recession in recent times and record losses in the aviation industry."

Earlier this week the International Air Transport Association said it still expected airlines to lose $11 billion this year, following a $17 billion loss last year, and warned that with jet fuel on the rise, cash flows would be under pressure. [ID:nL3308270]

The airline, which recently scrapped services from Manchester to Alicante and Malaga in Spain, did not say how many other routes would go but said it would "focus on routes and services that we believe are the best fit for our business."

Late last month Lufthansa's Chief Financial Officer Stephan Gemkow told Reuters TV it had shelved plans to sell BMI. [ID:nWEA7653]
