British airlines 'face multiple toxic air claims'
Seventeen former and serving cabin crew are planning legal action against British airlines claiming they have been poisoned by contaminated cabin air.
Workers believe they have fallen sick after breathing in fumes mixed with engine oil and other toxic chemicals.
The cases are funded by the Unite union, but the Civil Aviation Authority say incidents of smoke or fumes on planes are rare and there is no evidence of long-term health effects.
