Since I'm a passenger flights and general airlines enthusiast, I'd like to plan my travels and trips also depending on information on which kind of aircraft I'll be or can travel from point A to point B. For this reason, I'd like to ask some questions like "What is the shortest in-Europe commercial route that I can travel on Boeing 747" etc.
This particular question is found off-topic on Aviation.se and I was told that these kind of questions are also generally off-topic for that site.
And on Travel.se? Can such questions be on-topic here or should I avoid asking them here as well?
