I will be flying ECP (Panama City, FL) - ATL -LHR - NBO. The connecting flight to NBO is on Kenya Airways. I was hoping to remain airside for the entire layover, to avoid having to go through LHR security. Is the Molton Brown spa airside? It looks like the Yotel is landside, but I can't quite understand if the Hilton Hotel in Terminal 4 is. Also, at which terminal do inbound DL flights arrive and Kenya Airways depart? I will be in Bus. Elite, and wondered if DL has an arrivals lounge with showers. Would appreciate any suggestions.
