Left Sacramento around 11:30 am. Drove to Katherines apartment in SF. OVer 3 hours due to much traffic. Really muggy skies from fires. Loaded up Katherines bags and stuff to move home. Took back roads to SFO. Easy check in at SFO and we went to new Polaris lounge—many quiet spaces and amenities. They have a Buffett; a full restaurant with a menu, places to sleep, showers and anything else you can think of. We had a nice meal and a drink and relaxed until boarding time. Got on Lufthansa plane which seemed fairly new. We had business class seats that reclined totally flat and they even gave us a mattress pad. Unbelievable. They gave us Lufthansa night shirt. Unbelievable. They fed us, gave us a drink and we then went to sleep. We awoke just prior to breakfast then landed in Munich. Munich was very hot. Had 2 hour layover in Munich. Then boarded Aegean Airlines for Athens.
