Even though flight took off an hour late, we were able to make it to the connecting flight in Frankfurt thanks to Lufthansa crew. The ground crew was waiting at the gate and received us and took us through special runway entrance and immigration check. We were on the plane at 10-09 am for 10-10 departure. Thanks to Andre and the other lady for mission impossible :) The business class seat looked narrow, what I realised later is the ergonomics behind it. It was fitting the body very well and had best 6 hours sleep on a 9 hour journey..
