英国民航局批准希思罗机场有限公司从2024年起追回第三跑道扩建计划的3.2亿英镑前期支出[1]。这笔成本将通过提高对航空公司的收费转嫁给乘客，预计在20至25年内完全回收[1]。根据计划，2028年每位乘客的机场费用将增加约15便士，之后每年增加30便士[1]。
竞争方案希思罗西部也获得民航局批准，可追回410万英镑的相关支出[1]。英国航空公司对此表示担忧，警告早期成本回收可能使该扩建项目"对消费者不可承受"[1]。前财政大臣瑞秋·里夫斯曾表示要在本届议会任期内启动工程，目标在2035年前完成建设[1]。
The UK Civil Aviation Authority has approved Heathrow Airport Limited's plan to recover £320 million in upfront costs for its third runway expansion project starting from 2024, with the expenses to be passed on to passengers through increased airline charges over a 20 to 25-year period [1]. The cost recovery scheme will result in an estimated 15 pence increase per passenger in airport fees by 2028, rising to 30 pence annually thereafter [1].
An alternative expansion proposal, Heathrow West, has also been permitted to recoup £4.1 million in expenditure [1]. The expansion project has drawn criticism from British Airways, which warned that early cost recovery could render the scheme "unaffordable for consumers" [1]. Former Chancellor Rachel Reeves has stated the government intends to "break ground" on the project during the current parliamentary term, with a target completion date of 2035 [1].
