With fuel costs on the decline, it is quite evident that airline stocks are witnessing huge savings. With prices expected to remain weak going forward, carriers are likely to continue experiencing ample savings. For example, Delta Air Lines ( DAL ) expects to generate savings in excess of $3 billion in 2016 due to the fuel cost tailwind. It was this positive commentary that spurred a rise in Delta's stock price after its fourth quarter earnings release on Jan 19, despite it missing on both earnings and revenues.
