An eleven-year-old girl was denied the chance to make a long-planned visit to Platform 9 3/4 of King’s Cross station due to Heathrow disruption.
When Aleksandra Sobczak asked his nice Agata which place she would like to visit the most, she answered without hesitation: “London!”
“We are Polish and live in Warsaw. I’m a huge fan of the British Isles and of your extraordinary late monarch, and know London well for a foreigner, having been many times for work and pleasure,” Sobczak told the Guardian.
Sobczak went ahead and planned a surprise trip for Agata:
The trip was to be a surprise for Agata’s eleventh birthday. A London highlights bus trip for kids, Platform 9 3/4 obviously, Oxford Street window shopping, the Tower of London, Greenwich – the works.”
After months of planning Sobczak showed her niece the airline ticket last Tuesday on her birthday.
Clearing up my professional stuff yesterday morning for the London weekend ahead, I got the text message and the email. The airline was respectfully letting me know that, regrettably, the flight had been cancelled. Of all the days in the year? On a surprise my family and I had been planning for Agata for months? Then Agata’s dad texted me: ‘there’s been a fire at Heathrow’.”
Sobczak visited her niece on Friday evening with a conciliatory box of strawberry tarts and a hug.
We talked about Harry Potter and his Leicester Square statue. And the River Thames. We will see them in May.”

The substation fire was a “catastrophic failure” Robin Preece, a senior lecturer in future power systems at the University of Manchester, tells Sky News.
“Although we do sometimes see transformers or bits of electrical equipment fail, actually having them fail so catastrophically that they cause a large fire – which then leads the whole substation to be shut down – that’s what really tips this from being a more normal event into something that’s very, very unlikely,” he said
Earlier, transport secretary Heidi Alexander said the Department for Transport was “taking action to help people get where they need to be”, highlighting the news that the department had lifted restrictions on night flights to ease the backlog and rail tickets could be used flexibly to help passengers.
