There is no best option for the 220-240 seat market. Every available option has shortfalls:

Boeing 757-200:Terrible Fuel efficiency. Great range

Airbus A321-200: Decent fuel efficiency. Vastly inferior range

Airbus A321neo: Decent fuel efficiency. Inferior range

Is suppose the 757-200, in spite of it's fuel efficiency-issues, will solve a lot of headaches for a lot of players when they're sorting out their routes. That range is very, very handy.

I want to ask if it is better to start with long distance route or short one?And also how to keep finance good?Thanks You!

I'm a relatively new player myself, but I've found that medium to long distance routes (3k miles+) with no competition can be incredibly lucrative. If your world has been running for a while you can usually find some used older planes that have the range to make these distances, and if you stick to sectors with no competition then the higher fuel burn/maintenance cost of these old birds won't be a problem. Try to look beyond the obvious glamour destinations as those sectors are nearly always crowded. 

It sounds like an altogether more interesting challenge than flooding the skies with 20 year old A300s... Can't wait for the new world to kick off.

747-8i is a stunningly brilliant aircraft to have when possible, so profitable

Word. The A380 might technically speaking burn less fuel but it's too big for a lot of sectors. The 747-8i is unbelievably useful.
