I purchased a PMDG 737-7 yesterday and made my first flight today 
(I have only flown GA before, this is my first flight in such a large aircraft).
The route in Spain 
, Santander (LEXJ) to Malaga (LEMG).
Definitely feel the difference between small aircraft like Hjet or VisionJet
I fell in love all over again with this simulator 
At first I was terrified by the amount of switches, lights and all the rest in the 737, but it was enough to spend 2-3 hours learning and you can fly without any distractions or worries.
Greetings to all!
