I would really enjoy planes such as:
A319/320/321 Neo and the older versions
Boeing 737-8 max
Boeing 747-400 and -8
I must say I am not a huge fans of the Twin Otters or the Cessna Caravans. Not as planes as such but for them being used in actual airline service. I know they are used in the Maldives and in the Seychelles but I have never really seen them in Europe (where I live). I would like it more if they would just be used for the GA and not really pull up to actual gates.
