Well, this isn’t your everyday travel blogger scoop, but when Heathrow, the UK’s busiest airport, shuts down completely, it’s hard to ignore. A massive fire broke out at an electrical substation supplying the airport, and the result? Heathrow is officially closed today. No flights, no departures, no overpriced airport lattes.
Below, you’ll find tweets from major accounts, including Heathrow Airport and FlightRadar24, because when a travel meltdown like this happens, Twitter (or whatever we’re calling it these days) is where the chaos unfolds in real time. Passengers will not be entitled to compensation due to extraordinary circumstances, but airlines will assist passengers in reaching their final destination.

Conclusion:
If you hope for a smooth journey through Heathrow today, consider sitting tight or starting to check Eurostar schedules instead. With all flights grounded and no clear timeline for reopening, passengers are left scrambling for alternatives while airlines work through a logistical nightmare of rerouting and rebooking.
This isn’t just an inconvenience for those with flights today; delays and cancellations are likely to ripple across the network for days. If you have an upcoming trip through Heathrow, it’s worth checking your flight status frequently and considering backup options. Meanwhile, travel insurance might just be your best friend right now.
As always, WingTips will be keeping an eye on the situation (from a safe, non-electrically compromised distance). Whether you’re a stranded traveller or just here for the aviation drama, stay tuned for updates; we’ll bring you the latest as it unfolds.
