I will be arriving to NBO at 1:30 am ( flying from acc with a connection in add) am and I need to make my way to Wilson airport for an 8 am flight. Would I be permitted to stay in the airport and purchase a lounge pass for one of the 24 hour lounges ? Or will I have to pass through customs immediately and leave the secure area ? I am just looking for a place where I can spend a few hours before heading to Wilson airport.
