Of these, Vijay Mallya-owned Kingfisher Airlines has a due of Rs 295.50 crore, Jet Airways has Rs 82.17 crore while its subsidiary JetLite has Rs 27.62 crores.
Kalanithi Maran-owned SpiceJet owes Rs 58.77 crore, InterGlobe Aviation Ltd (IndiGo) owes Rs 9.26 crore and GoAir has a due of Rs 8.55 crore to the AAI, he said.

The minister said dues from privately-owned airlines are monitored on regular basis and in case of delay, the AAI issues notices to the airlines to settle the dues.
The AAI also charges penal interest on the delay in the settlement of these bills. In cases where delay persists, besides encashing the security amount the defaulting airlines are put on cash and carry basis, he added.

In 2010 and 2011, 21 such incidents were reported, he said. Last year there was a drop in airprox incidents and only 15 were reported but this year till January three incidents have been reported, he added.
