Fuel hedging hasn't translated into lower jet fuel prices for some of the biggest U.S. airlines, even after crude oil rose 17 percent in the fourth quarter.

American Airlines Group Inc., United Continental Holdings Inc. and Delta Air Lines Inc., three airlines that stopped fuel hedging, will pay the least for fuel this quarter, according to company projections. Alaska Air Group Inc. and Southwest Airlines Co. have hedged the highest portion of their fuel and yet will pay the highest and third-highest prices, respectively. The one exception is JetBlue Airways Corp., which stopped hedging this quarter but expects to pay the second-highest price.
