London Heathrow published three new Operational Advice Notices (OAN 518, OAN 548 and OAN 546) on 15 and 14 September, detailing overnight closures and traffic diversions that will affect airside logistics between 21 and 22 September. The most significant is OAN 548, which will close Hunting Way—an airside service road abeam Stand 432 at Terminal 4—from 22:30 on 21 September until 04:30 on 22 September. Vehicle traffic will be diverted across the stand itself under a marshalled one-way system. OAN 547 announces the closure of the ‘Cut-Through’ road adjacent to Stand 335 on 20–21 September, while OAN 546 covers a Pier 7 road diversion affecting stand-servicing routes used by ground-support-equipment (GSE) providers. Heathrow has warned all companies with airside permits that failure to brief drivers and contractors could result in penalty points under the Heathrow Airside Driving Scheme. For corporate travel managers the notices are a reminder that even short, overnight works can cascade into delays if fuelling trucks, de-icing rigs or crew transfer buses are held up. Firms operating private charters or time-critical cargo flights should cross-check slot times and confirm that ground-handling agents have contingency plans. Staff travelling on early-morning departures on 22 September should also allow extra time for potential knock-on security-queue impacts if GSE repositioning runs late. Heathrow’s OAN portal allows subscription to email alerts—a best practice for mobility teams managing VIP movements through the UK’s busiest business gateway.
