Airline tickets could cost more pretty soon. The government on 29 March revised several fees relating to the aviation sector, which airlines will doubtless need to pass on to the consumer. The decision raises the registration, renewal and ownership fees for airlines and also reduces fees relating to Air Operating Certificates (AOC). Registration fees for aircraft (including helicopters) up to 7,500 kg flight weight is Rs 22,950 ($300), almost double the existing rate, that for gliders is Rs 7,600, up from Rs 4,000. The AOC fee for international airlines, which was based on flight type, has been fixed at Rs 95,600 ($12,500), a significant reduction from the Rs 500,000 payable earlier (for charters it was Rs 300, 000). However?as if to balance the revenue losses?the government has raised the AOC fees for domestic operators to Rs 382,500 up from Rs 100,000 (and Rs 60,000 for irregular operators). The domestic industry, which was declared as sick some weeks ago and allowed to raise fares is perplexed, because the decision was taken without consulting the industry.
