I have a flight from LHR-NBO-LIV with 9 hours 45 min in NBO between flights. LHR-NBO is on BA and NBO-LIV is with KQ, all on 1 PNR. I saw a post on tripadvisor that you can't interline bags between BA and KQ and have to pick up the bags and recheck them.

1) Does anyone know if this is true (no interlining agreement) as I plan to stay airside and would prefer not to have a Kenya visa in my passport.

2) Does anyone have any experience of the different lounges at NBO as I see you can pay/ use PP to get into most of them. The 9+ hours is overnight so would be hoping for some sleep.
