A second financial issue is that of hedging oil and fuel purchases, which are usually second only to labor in its relative cost to the company. However, with the current high fuel prices it has become the largest cost to an airline. Legacy airlines, compared with new entrants, have been hit harder by rising fuel prices partly due to the running of older, less fuel efficient aircraft.[45] While hedging instruments can be expensive, they can easily pay for themselves many times over in periods of increasing fuel costs, such as in the 2000–2005 period.
The 1978 U.S. airline industry deregulation lowered federally controlled barriers for new airlines just as a downturn in the nation's economy occurred. New start-ups entered during the downturn, during which time they found aircraft and funding, contracted hangar and maintenance services, trained new employees, and recruited laid-off staff from other airlines.
After the funeral, C.C. tells Victoria that her mother wanted her to live with her, although several of her family members have asked. C.C. admits that she is very selfish and has no idea what kind of a mother she will make, but also tells her: "there's nothing in the world that I want more than to be with you". She then takes Victoria into her arms and the two console each other in their grief. C.C. goes forward with her concert, and concludes it singing "The Glory of Love," the first song Hillary heard her sing 30 years ago; as it ends, C.C. tearfully waves toward the sky, in tribute to her. After the show, she leaves hand-in-hand with Victoria, and begins telling stories of when she first met her mother. C.C.'s and Victoria's voices fade as we hear the younger C.C. and Hillary from 1958: "Be sure to keep in touch, C.C., OK?" "Well sure, we're friends aren't we?" The film ends with a young C.C. and Hillary taking pictures together, in a photo booth, on the day they first met.
Airline financing is quite complex, since airlines are highly leveraged operations. Not only must they purchase (or lease) new airliner bodies and engines regularly, they must make major long-term fleet decisions with the goal of meeting the demands of their markets while producing a fleet that is relatively economical to operate and maintain; comparably Southwest Airlines and their reliance on a single airplane type (the Boeing 737 and derivatives), with the now defunct Eastern Air Lines which operated 17 different aircraft types, each with varying pilot, engine, maintenance, and support needs.

In October 2015, Hawaiian Airlines announced that they will be upgrading their business class seats from the standard cradle seats to a 180-degree lie-flat seats on their A330 fleet in a 2-2-2 configuration. The new seats will be installed starting the second quarter of 2016. In addition to the new business class seats upgrade, the airline will add 28 additional Extra Comfort seating.[101]
