Munich Riem it is, despite the deliberate mis-steer of using Pan Am rather than LH images!
The Herald in the first photo was correctly spotted as op by Bavaria.
Part of the Riem perimeter was used for motor cycle and F2 car racing between 1949 and 1951. The Pan Am Connie was on its first visit to the airport in 1950 after post-war repairs. The Comet was United Arab SU-ALE after an overrun in Feb 1970 and the SAS Caravelle was bringing Wernher von Braun on a visit back home in 1960. The Lockheed Electra was of course G-AEPR arriving with Neville Chamberlain in Sep 1938.
The Junkers G.38 was an interesting beast - only 2 built and used by Lufthansa through the 30s. The second one, D2500/D-APIS, shown at Munich, carried 34 passengers including 6 in the wing roots - by all accounts, a very noisy and uncomfortable place to be. This particular aircraft was apparently destroyed in Athens by RAF bombers in 1941. The Japanese built 6 more as the Mitsubishi Ki-20 bomber.
Riem has long since closed but the iconic tall red tower survives in the exhibition grounds together with a token strip of runway.
