This more than serves a lot of purpose. Though these offers have a catch (not necessarily hidden), they make a lot of travel sense. I recently bought a return ticket to Zurich for Rs 14,500 (excluding taxes) which would have been unimaginable even months ago. The catch(es) usually are accomodating and require minor adjustmens, especially if you're travelling for leisure/holiday. I'm looking forward to a day when the market will be flooded with these kind of offers.
