Qatar Airways launched a three-day global sale to more than 100 destinations worldwide on Tuesday.
Passengers are being offered special fares with discounts of up to 25 percent off both Economy and Business Class prices, the airline said in a statement.
The round-trip fares are inclusive of all taxes and surcharges, the carrier added.
The 72-hour sale booking window ends on Thursday at 11.59pm.
Passengers are able to choose from more than 100 business and leisure destinations including Cape Town, New York, Sao Paulo, Bangkok, Athens, Singapore, Istanbul, Maldives, Delhi, Goa, Munich, Stockholm, Copenhagen, Casablanca and Melbourne via the airline's Doha hub.
The special fares are for travel until June 6, the statement said.
Qatar Airways CEO Akbar Al Baker said he expected the offers "to generate huge interest worldwide".
"2011 was a big year for Qatar Airways and 2012 is going to be even bigger as we introduce more destinations to our international network and increased capacity on existing routes to give our customers a wide array of travel choices," he said.
"We are very pleased to offer these great savings to our loyal customers, and to those travelling with us for the first time," he added.
Qatar Airways currently operates a fleet of 108 aircraft to 113 key business and leisure destinations worldwide.
