Sorry, I know it's not an AIBU but I am struggling to find official information regarding passengers arriving at Heathrow.
IATA's website seems to list every country in the world except the UK.
DH has been stuck overseas and has a chance to get out of the country he's in this week but it doesn't look like he'll arrive in time to get a connecting flight to our country the same day.
There are no airside hotels in LHR so he'll have to clear customs and immigration and stay in a hotel. I'm not even sure if that's allowed.
Has anyone seen this information anywhere that they could direct me to, please?
Thank you!
