This multi-series line graph shows the number of monthly landing count by aircraft manufacturers with an average landing count of 300 or more. As a result, small aircraft manufacturers are omitted. Hover over the graph to see the landing count of each manufacturer during the specific activity period.

There are some notable findings that are prominent in this visualization:

• Boeing was the most popular aircraft manufacturer among the airlines that operate at SFO.
• Airbus was trailing behind Boeing as the second most popular aircraft manufacturer among the airlines that operate at SFO.
• Embraer and Bombardier, both regional airliner manufacturers, were in a cat-and-mouse chase, with Bombardier in the lead for most of the duration.
• McDonnell Douglas, which merged with Boeing in 1997, was in the process of being phased out by airlines that operate at SFO.
• Traffic for Boeing and Airbus peaked during the summer, in July, and dropped during the winter, in January, every year at SFO, while other manufacturers were largely unaffected by this cycle.

This comparison chart shows the percentage of Boeing aircraft models for domestic and international flights. Each plane represents one Boeing aircraft model. While it is true that the size and shape of the each model are different to one another, one generic shape was chosen for easy comparison. Hover over the planes to see the actual landing count for domestic and international flight of that model and their respective percentages.

There are some notable findings that are prominent in this visualization:

• B717 was exclusively used for domestic flights, presumably due to its small capacity and short range.
• B747 was almost exclusively used for international flights, presumably due to its large capacity and long range.
• B717, B727, B737, B757, and B767 were more commonly used for domestic flights.
• B747, B777 and B787 were more commonly used for international flights, presumably due to their large capacity and long range.

There are some notable findings that are prominent in this visualization:

• A300 and A310 were exclusively used for domestic flights, presumably due to their small capacity and short range.
• A321 was almost exclusively used for domestic flights.
• A318, A319, and A320 were more commonly used for domestic flights.
• A330 was more commonly used for international flights.
• A340, A350, and A380 were exclusively used for international flights, presumably due to their large capacity and long range.

This stacked bar chart shows the landing count of airlines per aircraft manufacturer. Only airlines with more than 35,000 landing counts are included since they are relatively more important. Hover over the legend to see the actual landing count of that aircraft manufacturer in each airline.

There are some notable findings that are prominent in this visualization:

• United Airlines had the largest number of landing counts, which meant that it had the largest market share at SFO. (Note: SFO is one of the hubs for United Airlines)
• Virgin America and JetBlue Airways used Airbus aircraft exclusively for flights to SFO. (Note: Both airlines have an all Airbus fleet)
• Southwest Airlines used Boeing aircraft exclusively for flights to SFO. (Note: Southwest Airlines has an all Boeing fleet)
• U.S. Airways (Now merged with American Airlines) and Air Canada used Airbus aircraft for the majority of their flights to SFO.
• American Airlines, Delta Air Lines, and Alaska Airlines used Boeing aircraft for the majority of their flights to SFO.
• American Airlines was the largest user of McDonnell Douglas aircraft for flights to SFO.
• Alaska Airlines was the largest and the only user of DeHavilland aircraft for flights to SFO.
