Northern airlines merged Southeast Airlines to create the fourth largest U.S. carrier in which it inherited both an aging fleet of Boeing 737-300 aircraft and Stephen Ruth. As the new president of the airline, Stephen’s first concern is to create a financially solid company since it is a common presumption for airline industries that maintenance costs rise with the age of aircrafts.

He noticed that there have been significant differences in the reported B727-300 maintenance costs both in the airframe and engine areas between Northern and Southeast Airlines, with Southeast having the newer fleet. He asked Peg Jones, Vice President for Operations and Finance to investigate on this issue and to know whether there was a direct relationship between average fleet age and direct engine maintenance costs.

Definition of Problem
Peg Jones must be able to determine if there was a correlation between the average fleet and the maintenance cost. She must also find out if the average fleet age is related to the direct engine machine costs. Jones must be able to provide his findings to Stephen Ruth, who is the new president and chairman of the board of the two airlines, for them to be able to properly investigate and address the issue.

The following are the available data to be used to help Ms. Jones in the determination if there was a correlation between average fleet and the direct maintenance costs. The following steps were performed by Ms. Jones and her staff:

* The staff constructed the average age of both fleets, by quarter. * The average age of each fleet was calculated by first multiplying the total number of calendar days each aircraft has been in service at that time. * The average utilization was found by taking the actual total fleet hours flown on September 30, 2007,...

911 Attacks

...On September 11, 2001, at 8:45 a.m. on a clear Tuesday morning, an American Airlines Boeing 767 loaded with 20,000 gallons of jet fuel crashed into the north tower of the World Trade Centre in New York City. The impact left a gaping, burning hole near the 80th floor of the 110-story skyscraper, instantly killing hundreds of people and trapping hundreds more in higher floors. As the evacuation of the tower and its twin got underway, television cameras broadcasted live images of what initially appeared to be a freak accident. Then, 18 minutes after the first plane hit, a second Boeing 767–United Airlines Flight 175–appeared out of the sky, turned sharply toward the World Trade Centre and sliced into the south tower near the 60th floor. The collision caused a massive explosion that showered burning debris over surrounding buildings and the streets below. America was under attack. The attackers were Islamic terrorists from Saudi Arabia and several other Arab nations. Reportedly financed by Saudi fugitive Osama Bin Ladens al-Qaeda terrorist organization, they were allegedly acting in retaliation for America's support of Israel, its involvement in the Persian Gulf War and its continued military presence in the Middle East. Some of the terrorists had lived in the United States for more than a year and had taken flying lessons at American commercial flight schools. Others had slipped into the country in the months before September 11 and acted as the "muscle" in the operation. The......

2013 Headwinds over South Africa

...Fastjet Airlines Words: Keith Mwanalushi Headwinds over South Africa In the past few years the South African domestic market has had a bumpy ride. The local airline industry has witnessed the demise of 10 out of 11 independent private airlines since deregulation in 1990. This raises the question as to how new entrants will survive. 22 FlightCom Magazine Fastjet; entering South African domestic market. A consistent theme across the global airline industry is one of poor return on investments; protected competition; low barriers to entry and the high status associated with owning an airline; an industry that is a soft target for taxes; volatile costs; labour issues as well as increased regulation. South Africa is no exception. “Airlines operating in the domestic South African market face both demand and cost pressures,” says Carlos Ozores, Principal at aviation consultants ICF SH&E. “On one hand, South Africa’s economy is growing very slowly by emerging market locally the industry is challenged by a small market; inexperienced new competitors with inadequate equipment distorting the market; regulatory oversight; monopoly suppliers; state-funded competition; challenges with fuel supply, as well as skill shortages. “The weak economy and poor consumer spend; high oil prices, excessive supplier charges and the weakening local currency all threaten the growth of local air travel.

South Africa and Anglo American Plc

... Connecting within Oneworld Following 2010 approval by U.S. and Japanese authorities for antitrust immunity, American Airlines (AA) and Japan Airlines (JAL) began sharing routes in 2011 that connect mainland North America with East Asia through a nonequity joint venture. Flights between Honolulu and Japan are not included in the agreement. This joint venture is similar to one forged among AA, British Airways, and Iberia for trans-Atlantic travel that began operating in 2010. In both cases, the agreements allow representatives from each airline to jointly manage capacity, sell and promote space on flights operated by each other, divide revenues, and schedule connecting flights. The major thrusts for these ventures are to cut operating costs by better controlling capacity, avoid disruptive price competition among them, and schedule so that there are more and better departure times and connections for passengers. The proposals are merely extensions to a historical series of alliances linking international airlines. In fact, the airline industry is unique in that its need to form collaborative arrangements has been important almost from the start of international air travel because of regulatory, cost, and competitive factors. In recent years, this need has accelerated because of airlines’ difficult profit performance. In effect, the airlines have been squeezed. First, costs have been rising, particularly because of oil prices and the requirement for greater......

Singapore Airlines

...Singapore Airlines’ history can be traced back to 1 May 1947, when a Malayan Airways Limited (MAL) Airspeed Consul took off from Singapore Kallang Airport on the first of three scheduled flights a week to Kuala Lumpur, Ipoh and Penang. · Over the next five years, larger capacity DC-3 aircraft were introduced. This meant faster and more comfortable flights, and the extension of services to destinations in Indonesia, Vietnam, Burma (now Myanmar), North Borneo (Sabah) and Sarawak. · Inflight refreshments improved from the original thermos flask of iced water to sandwiches, biscuits and cold cuts plus a choice of hot and cold drinks, and alcoholic beverages served by a lone hostess. Known as “female pursers”, these hostesses are the forerunners of today’s Singapore Girl. In May 2008, Singapore Airlines created history again by being the first carrier to operate an all-Business Class service between Asia and the USA with its launch of all-Business Class non-stop flights from Singapore to New York (Newark). After operating as Malaysian Airways and then as Malaysia-Singapore Airlines, SIA was officially launched in 1972.

Delays caused by poor planning and repeated design changes pushed the opening day back, first to December 1993, then to March and finally to May 15, 1994. In April 1994, the city invited reporters to observe the first test of the new automated baggage system. Reporters ended up watching clothing articles and personal items scattered all over the floor. The mayor cancelled the planned May 15 opening. The airport collects landing fees, rent and other revenues from the airlines to help offset its operating costs. Denver International Airport is owned and operated by the City and County of Denver, but does not operate using tax dollars. Instead, the airport is an "enterprise fund" generating its own revenues in order to cover operating expenses. The airport operates off of revenue generated by the airlines – landing fees, rents and other payments – and revenues generated by non-airline resources – parking, concessions revenues, rent and other payments.
