Thanks for the advice.
I didn't know about the 75-80 LF rule. I will need to increase prices as many routes have above 90 load factor (i could could add more frequencies on some).
Of 88 aircraft, I own one A320! and have orders for 30 x A320neos and 45 350's - all leased - I've just realized that the high lease costs alone on brand spanking new planes may overtake any fuel saving advantages and kill my profits!
May concentrate on converting leases to purchases, but could also just cancel (at the cost of a $billion or so!) and consolidate my current fleet.
I don't know if I would call it a "rule" more of a trick to help increase the income a little bit
. If you are going for an airline that has 100% LF, then it doesn't help much. As long as your at around 75-80% you can hit the sweet spot between maximum income, and maximum load.
And yeah, you absolutely should focus on owning aircraft, at least half, as Tvdan suggested. You don't have to cancel the ones you are getting, but make sure from now on that you focus on buying airplanes, and preferably from the UM to begin with. I mean, it's better to break even on those leased planes, and spend that billion on buying out planes you already have leased, or creating new routes with planes you've bought.
As for converting leases to purchases, its a complex issue. Don't bother buying out an aircraft if it has a very long lease on it; you have to pay for breaking the contract, and basically all the years that you broke the lease for. As you can imagine, it can really cost you a pretty penny. Also, don't bother buying aircraft that are really close to their D check, anything less than 2 years away is asking for trouble, especially when you consider that D checks can cost millions.
The best strategy I would suggest is to look through your leased planes. Those that are close to D check, let the lease run out. Those that have a very long lease (2 years + roughly), don't buy out, either way for the lease to run out a little or just let the lease run out. The airplanes that have a short lease, and are far away from D check are the primary planes you should be aiming for. *
Also, a nice thing to do is when you let a lease run out, you can replace that planes with one you bought off the UM. It doesn't require you to figure out new routes and it "converts" a leased plane to an owned plane. So its a basic switch.
Finally, I'm not quite sure how used you are to the used market, but you should be aware that you can't lease/buy more than 2 airplanes a day, and 3 airplanes in a week.
Edit: * You should keep in mind that the game automatically extends leases if they finish, so you have to keep an eye out for that
. You can switch it off, and the game should message you when you get really close to running out the lease.
I also want to add that I'm insanely tired and about to pass out, so if some things don't make sense, just point them out and I'll clarify when I wake up
