Airline operations staff spend a lot of time making sure they are getting the most out of their aircraft. That means using the right aircraft on the right route. For some airlines, like Southwwest or easyJet, that problem is solved by having one type of airplane and a route network that fits the aircraft’s performance. For others, like United Airlines or Qantas, it means having multiple types of aircraft for different missions. We took a look at a week (Saturday, 27 February — Friday, 4 March) of flying for three different kinds of aircraft in the United Airlines fleet—Embraer E175, Boeing 737-900ER, Boeing 787-9—to see how each is used by the airline.

United and its regional partners operate a fleet of 127 Embraer regional jets in the E170 family, which includes the E170 and E175. N103SY is an E175 operated by SkyWest Airlines under the United Express brand. Over the course of the week, N103SY visited the east and west coasts of the United States, but did most of its flying through the United hubs in Chicago and Denver. Beginning in Austin and ending in San Francisco, N103SY completed 25 flights, visiting 15 different cities.
