Mohammed Zafar, a manager at Akbar Travels of India, said he stopped selling Kingfisher tickets after the International Air Transport Association (IATA) suspended the airline from its clearing house for failure to pay its dues.
"With each passing day, the number of flights become fewer. How can we issue tickets if we are not sure about the airline?" Zafar said in New Delhi.
While Mallya has his detractors, his team says he is working strenuously to pull his airline back from the brink.
"It's just the solutions never came ... attempts were made, but no solutions. The hope of promise from A party or B government or C guy never came," said the former Kingfisher director.
