Hi there! I arrive at 23:00 in Heathrow airport and don’t depart until 11 the next day. I’m flying business through BA.

I don’t really want to leave the airport. Are there any lounges open overnight or do all of them open at 5:00?

Would love to shower and relax. Are there any hotels attached to the airport where I don’t have to leave and go back through security?
