Now a days I have received some from via.com about cheap air flight ticket
( Dear Friend, via Fly @ 601* Super Sale on Domestic Flights Book Now Only a Few Hours Left! Hurry!)
above same advertisement come every 10 days in my mail they offering various cheap rates of flight. but when you open same page you found nothing.
other travel company like make my trip / yatra / cleartrip at least they describe their advertisement properly and I honestly said even I had travel with makemytrip many time with lowest airfare and their cheap air flight ticket offers.
