I mostly do regional flights because they dont take much time and I get to practise buttering the bread. Here is my list:
Porter Q400 LaGuardia-Toronto City: the City airport runways are challenging
Flybe E195 Southampton-London: This I sometimes do when theres not much time, but it might be too short
Singapore 78X or Cathay 777 Singapore-HK: This is really close to 4 hours IRL, but it really doesnt take that long. The Hong Kong 25L approach I really like for some reason, and the mountains before the approach is pretty nice for screenshots.
Swiss A319: Zurich-Milan: the Swiss Alps is quite the view.
Air Canda CRJ-200: Thunder Bay-Sudbury: I’m a Canadian, so I naturally have a like in this. And Poutine. Canadian airline, or a canadian plane, over canada. Dont question me.
JAL 747-200 or MD-11, anywhere between Sapporo New Chitose, Tokyo Haneda, Narita Chubu Centrair, Osaka Kansai is nice, with the mountains. Also Chubu, Kansai, are on landfills which look nice in my opinion.
I fly a lot of different stuff cuz im a weird guy, my most flown is probably the zurich-milan
