About 7,000 people are reportedly affected after Spanish airline Air Comet's fleet was grounded this week by officials over its failure to pay debts, Colombia Reports reported. The low-cost Spanish carrier owes €17 million to Germany's Nord Bank in lease payments and Air Comet says it is seeking to lay off all of its nearly 700 employees. The Madrid-based company - which specialises in cheap flights to Latin America - also says it has filed for bankruptcy.
