The company reported net earnings of 529 million euros ($580 million) for 2015's second quarter, up from 173 million euros in the same period last year. Total revenue came in at 8.39 billion euros, an 8.9 percent increase from 2014's second quarter.
Despite the lift from cheap oil, Lufthansa is currently in the midst of dealing with disputes between its labor force and over compensation with the families from the March crash of an aircraft operated by its subsidiary Germanwings.
Market shares in Lufthansa may have sunk after the news in March, however, the airline doesn't see any financial impact on it or either.
Simone Menne, Chief Financial Officer for Deutsche Lufthansa AG, told CNBC on Thursday that the outlook for Germanwings was looking good in terms of bookings, expecting it to break-even.
"Of course it was a very, very tragic case. Regarding the figures (though) we don't see any impact at the moment. Actually Germanwings is performing very well, with high volumes during summer and the outlook looks good. So I don't see a financial impact. Germanwings will break-even this year."
In terms of the families and compensation, Menne said Lufthansa preferred not to discuss the process in the media, however, stressed that they talked to the relatives "in all respect directly."
In its earnings, published Thursday, Lufthansa attributed its lift in profits to the 309 million euro reduction in its fuel costs, along with a rise in sales and capacity utilization.
"The oil is definitely helping us. In the first half year, that was really a huge tailwind and also for the rest of the year we see the oil prices will stay low, and at least on the short-term does help. We have reduced our prognosis for the oil to 6 billion from 6.2 billion," Menne told CNBC.
However, Menne admitted that with more affordable pricing from other competitors, this was causing pricing pressure.
"We see that the pricing pressure is there and will continue to stay, as the low cost carriers are entering into our home markets. On the other hand, we are well prepared, because we have our new platform, Eurowings, with a different cost space than the premium platform."
"We are pretty sure than our new fares structure is fitting into the market and the needs to our customers. The individualized possibility to buy what you need helps our passengers, and the transparency makes everybody see that we are very competitive in our pricing I don't think this is a risky strategy."
Stocks in the airline rose 3.5 percent in early trade, making it a two month high for the firm, according to Reuters. However, by the close, the stock had pared gains to close around 2.8 percent lower.
