I know there have posts about this, but I figured I'd post my problem anyway. I just put a Q400 on the market with a minimum price of $19,300,000 (it's actual value) and it sold for about -$340,000. It doesn't hurt me that much, but I'm still not happy about paying someone to take one of my planes.

I looked through previous posts on this topic, but wasn't entirely sure of something. If I build a terminal at an airport, does it have the same load factor benefits as a hub? Or do I then need to make my terminal into a hub to get the load factor benefits?

I noticed that Taipei was not in range for any flights I tried to send there with a Q400. Even from some cities pretty close to where it is shown on my atlas, there was still insufficient range. So I'm not sure where AE thinks it is.

There may also be a second one, but it may very well be just me. Ever since the game restarted, firefox consistently freezes on me when I'm at AE. It only does this at AE. IE works just fine, though. Has anyone else been having a similar problem? Or is it just something weird with me?

I saved up to buy an A330-300 and when tried to buy it, but when I clicked on 'Confirm Purchase' it went to a screen that said hacker alert. I don't know what happened or why it did that. Any help?

A couple months ago (in sim time) I was making about $650,000/day. Over the past few months, my profit has been steadily decreasing. I haven't changed anything, and I don't think there has been a significant change in competition in my routes. What may be causing this? Am I missing something in my management? Or is there some sort of novelty in passenger demand where the longer you are on a route they fly on you less? Is it aircraft depreciation in profit generation on the route? Or is it some sort of market swing that is happening to everyone? I checked some competitor's financial sheets and some seem to be having the same 11-20% decrease in profitability I have been having.
