Ajay Singh, CMD, SpiceJet shares that apart from ATF, excise duty is another issue that the aviation industry is dealing with. “It’s not just about bringing ATF under GST, it’s also excise duty, which is around 11%. The excise duty was hiked at the time when oil prices went down. Now that oil prices are at a record, excise duty is not coming down. Hence, we need to be very cognizant of the fact that aviation sector has suffered huge losses. It’s a chronically ill industry,” he said.
