Okay, making the changes suggested in your reply, Fleur-de-Lis and noting them as I make the changes.
1st point about the aircraft, I had trouble finding the specifications on the airplanes especially my starter airplane and the distances between different airports which resulted in renting some gates that were too far away from Orlando and then returning them when found out could not run to them (OUCH!! BIG money water there!)
Go to the "View and Buy" menu (Under "Aircraft" tab in game). There's something marked to the right of all aircraft in that list called "Info". Click on that for all the planes specifications.
Go to the "research Route" menu (Under the "Routes" tab in game). Then input the names of the origin / destination airports. It'll give you the distance, as well as, which aircraft types can actually run that route. Do that first, if you are unsure - before buying gates and spending route research costs needlessly.
A lot of this can be answered if you would read the Game's Manual. Admin tab in game, Game Manual menu.
2nd point, I have returned the extra gate but I now have two at MCO and one at Atlanta - should I return the second MCO gate? Was not sure since you mentioned my having only one extra.
If you believe that you can fill at least 11 slots from Orlando (but from what you're saying, I doubt you'll get the money for additional aircraft now) before the month changes, then keep them. If not then return one. I nearly always return one of my two starting gates when I start a new game.
3rd point, I changed to only a single frequency and find that with some fiddling around with the ticket prices by comparing with the competition there that I seem to be maximized for possible earnings on the route I am running.
Good.
4th point, I originally started running between MCO and Melbourne International (which is in Melbourne, FL as I well know because I have flown to/from it when visiting my relatives in Florida) but returned the gate there when I figured out I could make more money flying between MCO and ATL.
You'll make more money flying many short routes, compared to a few longer ones. But you'll learn this soon enough.
Not saying it is wrong to fly to Atlanta, in fact it a generally a good thing to fly to the largest airport in the whole game. I was just giving a general strategy above. If my plane could only fly once to Atlanta in a day, compared to flying to five or six smaller airports, I would forget ATL till later on. It's just basic math.
5th point, I will keep this particular thread bookmarked so it will be easy to find when I have enough money to buy another plane.
I'd change the thread title to something like: " New Player Advice Needed - World #9". You can edit it in by clicking on the "edit" button. Soon enough a moderator will move the entire thread to the General Chat forum. This does not belong in the Alliances forum any more.
6th, 7th, 8th and 9th points are best for me to keep uppermost in my mind for this game - but as to MCO being considered to be a very large airport, maybe I should have taken Melbourne International (MLB) as my home city (heck, I grew up there so I am pretty sure that is considered a smaller airport, I know they cannot take the bigger airplanes there in real life, they tend to use regional aircraft to fly into there).
This "game" does not reflect real life in many aspects. It's generally considered better to start in cities with large PAX amounts, if your goal is to become a monster airline. That's every airport with a gate cost of 350K.
Other people try to mimic real life airlines, while others play for other goals. All depends on what you want to do.
