Heathrow Airport has issued an alert that no Piccadilly line trains will serve any of its four terminals from Thursday 28 May through Sunday 31 May due to major signalling upgrades. The closure severs the only direct Underground link between the airport and central London, forcing passengers onto alternative services just as the late-May holiday rush peaks. Heathrow Express and Elizabeth line trains will continue to operate to Paddington every 15 minutes, but both operators expect heavy crowding and have suspended off-peak fare promotions.

TfL has arranged rail-replacement buses between Acton Town and the airport, yet journey times are likely to at least double compared with the usual 50-minute Tube ride from the West End. Airlines have updated their pre-departure emails to highlight the works, and several Asian carriers have extended check-in cut-off times to accommodate delayed passengers. Travel-management companies are advising corporate travellers to budget an extra hour for the airport run or to switch to a fixed-price car service to avoid queuing at rail ticket machines. The four-day shutdown is part of a £1 billion modernisation programme intended to enable 36 trains per hour on the western end of the Piccadilly line by 2030, coinciding with the arrival of new walk-through, air-conditioned rolling stock. While business groups back the investment, they argue that future blockades should avoid bank-holiday periods or come with discounted Heathrow Express fares to mitigate the impact.
