LONDON- Heathrow Airport (LHR) in London is investigating ways to reduce expenses for its planned expansion, including the possibility of constructing a shorter third runway, according to a Financial Times report published Saturday (March 8, 2025).
Sources familiar with the situation revealed the airport is evaluating all available options before finalizing its decision.

One alternative under consideration involves proceeding with the northwestern expansion using a shorter third runway, which would eliminate the need to divert London’s M25 motorway through a tunnel. The airport is currently assessing the feasibility of this approach.
Heathrow Airport CEO Thomas Woldbye announced last month that a third runway proposal would be submitted this summer, shortly after the government endorsed the project, citing its benefits for trade and economic growth. Woldbye indicated that a third runway could become operational by 2035.
The airport currently operates at full capacity with its two existing runways and can only accommodate additional passengers when airlines utilize larger aircraft. By comparison, European competitors Paris and Amsterdam operate with four and six runways respectively.

London Heathrow Airport (LHR) commands the highest airport slot prices globally, with limited availability creating intense competition among airlines. These coveted slots provide essential access to one of the world’s busiest aviation hubs and carry extraordinary valuations in the industry.
Heathrow slots represent crucial operational rights beyond simple scheduling allocations. Airlines securing these slots gain entry to a premier global market, though this access requires substantial financial investment and navigating complex logistics.
The airport operates at nearly maximum capacity, transforming slot acquisition into one of aviation’s most competitive business activities. Slots enable carriers to schedule operations during specific timeframes and utilize Heathrow’s runways, gates, and terminal facilities.
EU regulations established in the 1990s govern slot allocation, ensuring fair distribution while creating significant barriers for new market entrants who must invest heavily or negotiate to obtain slots. The secondary resale market for these slots demonstrates their exceptional value, with transactions typically conducted confidentially.
Morning slots, particularly valuable for profitable transatlantic and Asian routes, command premium prices, exemplified by Oman Air’s record-setting $73 million slot purchase in 2016. Evening departure slots, while less desirable, still rank among the most expensive airport slots worldwide.
