Overnight Layover- DATV

Overnight Layover – DATV Query
Hello, I’m having trouble finding clear information regarding the Direct Airside Transit Visa (DATV) for an overnight layover at Heathrow Airport (LHR).
I’m reaching out on behalf of a Chinese friend who has an approved DATV for an overnight layover. She arrives at night and departs the following morning within 24 hours. Since her tickets were purchased together, her luggage will remain airside and won’t go through border control.
However, I’ve come across conflicting information. Some sources state there’s no airside transit hotel at Heathrow and that she cannot sleep in the airport, suggesting she would need to exit and re-enter through border control, which isn’t an option with a DATV. Other discussions indicate that it’s possible for her to stay in Terminal 3 overnight.
She also tried to apply for a Visitor in Transit Visa to simplify the situation, but that application was denied. So, the DATV remains her only option.
Could someone clarify the correct information for me? I want to ensure my friend doesn’t face any issues on her journey. Thank you!
It can be quite confusing navigating the rules around the Direct Airside Transit Visa (DATV), especially for overnight layovers at Heathrow Airport. Here’s the information that might help clarify the situation for your friend:
DATV Holders: If your friend holds a valid DATV, they can transit through the airport without going through UK border control, which means they can remain airside.
Staying Airside: While Heathrow does not have airside transit hotels, passengers are typically allowed to stay in the terminal overnight if they have a confirmed onward flight and remain within their designated terminal. This means your friend should be able to stay in Terminal 3 until their next flight, provided they do not exit the airside area.
Sleeping in the Airport: While it is generally allowed to remain in the airport, it’s important to consider that policies may vary by terminal, and services like seating might not be as comfortable for overnight stays. It would be advisable for your friend to bring a sleeping bag or something comfortable for the night since seating might be limited.
No Need to Leave: Since your friend has an approved DATV and their luggage will be transferred seamlessly to the next flight, they do not need to exit the terminal or go through border control. Exiting would invalidate their DATV status and could lead to complications.
Final Recommendations: It would be prudent for your friend to double-check with the airline for any specific guidance they may have for overnight layover passengers. Additionally, staying updated on any airport announcements can help in case of any changes to policies.
In summary, your friend should be able to remain in Terminal 3 overnight with their DATV as long as they do not leave the airside area. It may be a bit uncomfortable, but it is generally allowed. If in doubt, reaching out to airport staff when they arrive can also provide reassurance and guidance.
