The original post was very innocent......but I feel a major A vs. B war coming on and lets try to avoid it.
So many factors are involved in purchasing aircraft, remember how expensive an airliner is, and a major order runs into billions of dollars/euros, so the desicion is a huge one and I do not personally think that politics or country of origin are a major factor in the decision making process. Remember that a huge amount of content in Airbus airliners comes from the US, and a huge amount of content in Boeing airliners comes from Japan, China and other far off lands, so its not nearly as simple as America vs. Europe as some may suggest.
1. The most important issue is the aircraft's mission.....an airline buys the types that is needs. Also keep in mind that decisions are made by what is available at the time that the order is being placed - the 737NG is great, but if an airline made its narrowbody fleet decision before that type was launched, the airline may have looked to Airbus.
2. Money, price, terms, support packages.....all of the financial stuff is a very key factor and often the deal maker or breaker.
3. Delivery times......manufacturers do not have airliners in inventory, and it takes a long time for a fleet of aircraft to be delivered. If Airbus cannot deliver a fleet of A320s to an airline within the time frame desired by an airline, they may buy Boeing instead for that reason alone.
4. Leasing companies influence airlines.....if a large lessor has several of one type available, the airline may go on to order the type as well.
5. Commonality - msot airlines stick with one type for a specific mission, we dont see many carriers flying the 340 and 777 side by side (although AF
does, for example) and we dont see many flying the 73G and A321 (but SAS does).....it depends on economics and fleet size.
6. Tradition - certain airlines are long time customers of A or B and prefer their products.
7. Politics - of course politics are involved and politicians will stick their noses into situations where they do not belong - billions of dollars/euros in orders and thousand of jobs are at stake, politicians will take notice.
8. But remember, carriers worldwide want both Boeing and Airbus, and Embraer and Canadair to stay in business. All Airbus or All Boeing fleet propoganda is nonsense.....only if the manufacturers all stay in business will new and more effecient and more advanced products become available, and only if all the manufacturers stay in business can the airlines negotiate and obtain aircraft at market prices. You can be sure that Lufthansa, which flies more and more Airbus aircraft, takes a very serious look at any new product offered by Boeing and even CO
, which is very pro-Boeing, studies what Airbus has to offer.
