Passenger kilometers flown by airline worldwide 2020

The three largest U.S. full-cost carriers sit atop the list of passenger kilometers (RPKs) flown worldwide in 2020 with American Airlines managing to reach top spot with 124 billion RPKs. On the third place was Delta with 106.5 billion, followed by United Airlines with 100.2 billion RPKs.Revenue passenger kilometersRevenue passenger kilometers (or revenue passenger miles, in some territories) are a measure of passenger demand in a given market. They are calculated by multiplying the number of revenue-paying passengers aboard an aircraft by the distance the aircraft traveled. Often RPKs are compared to available seat kilometers (ASKs), which are the number of seats available for sale on an aircraft multiplied by the distance flown. ASKs effectively measure supply in a given market, with the goal of airlines being to match their ASKs offered with their RPKs flown.Airline metricsAcross most airline industry metrics the large full-cost U.S. airlines dominate. Looking at only the number of passengers flown, American and Delta again sit in first and second place, with U.S. low-cost carrier Southwest coming in third just ahead of United. Revenue figures tells a similar story, but with German national carrier Lufthansa replacing Southwest. However, when considering the number of airport pairs served, all the U.S. carriers are beaten out by Irish low-cost carrier Ryanair, who serve nearly 50 percent more airport pairs than American Airlines.

在2020年全球航程旅客公里（RPKs）排名中，美国三大全成本航空公司位居前列，美国航空公司凭借1240亿RPKs的成绩成功夺魁。排名第三的是达美航空公司，其RPKs达到1065亿，紧随其后的是联合航空公司，其RPKs为1002亿。航程旅客公里（或在某些地区称为航程旅客英里）是衡量特定市场旅客需求的指标。它通过将飞机上的付费乘客数量与飞机航行的距离相乘来计算。RPKs通常与可用座位公里（ASKs）进行比较，可用座位公里是指飞机上可供销售的座位数量乘以航行的距离。ASKs实质上衡量的是特定市场的供应量，航空公司的目标是使提供的ASKs与实际飞行的RPKs相匹配。在航空业的大多数指标中，大型全成本美国航空公司占据主导地位。仅从运输乘客的数量来看，美国航空公司和达美航空公司再次位居第一和第二，美国低成本航空公司西南航空公司排名第三，略高于联合航空公司。收入数据也呈现出相似的趋势，但德国国家航空公司汉莎航空取代了西南航空。然而，在考虑服务的机场对数时，所有美国航空公司均被爱尔兰低成本航空公司瑞安航空超越，瑞安航空服务的机场对数几乎是美国航空公司的50%。
