the fact you are running Shorts 360 makes you a Spamliner

I'm losing like 200K on it.  everytime I pull back flights, that other guy gains though.  

Hexagon,

If you are talking about Sandbox #4, PSI also confuses the crap out of me. 

Btw, thanks for not starting huge fare wars like the guy we compete with --   DCA/BOS is a bloodbath and it shouldn't be.   Was hoping some capacity dumping would work, but no.   the one guy flying nothing but Q300s also intrigues me.

the longer you keep a plane, the more expensive the engines become each month. 

Also, when you try to change one aircraft's line (schedule) to another, keep in mind that some planes are faster/slower than others, and bigger planes require more turn time on the ground - so if you tightly schedule each line to have no more than 10 hours open, you may find yourself in a difficult position or have to not move over all the routes.  So keep an eye on those hours.

In the sandbox, I'm doing a lot of what this person is asking.  Upgauging B717 flights to B738/B739ER (yes, the 900 is worthless), or upgauging EMB 175s to B717s; B763s to 77W or 772's, etc.   Just have to keep your eye on the # of flights.

And also, if you are going from one configuration to an other (such as C / Y to a plane with F / Y), you'll need to double check your fares as well.

Few notes as I play around:

Finances -> Try not to have high-value aircraft leases in the first few days of the month.  The game tends to suck out all your gate fees, maintenance fees, and others at the 1st  & 13/14th of each month.  Which means you need to stockpile money after the 20th.  But if there's not enough money, any leases / bonds due at the front end of the month will not clear and you risk default.

Days of months -> It seems the game operates off 24 days a month, NOT 30.

On Time Performance -> I've found if I leave about 20 hours free on each airframe, that tends to help keep On Time in line.  

Inflight Service -> I use F/C in smaller cabins, but have a different service for those where they get free food (level2/3) but can pay for level 5.  

IFE -> Same as above, I can differentiate between awesome free stuff for premium cabin vs pay for it in back.  I try to keep IFE settings at 3 and ads at 1 hour.

Gates -> some are SUPER duper expensive, and that money comes out at random it appears.  I try to maximize my slots at all airports and connect dots if the game scenario allows it.  This is especially important at very large/expensive airports like LHR, PVG, ORD, etc.  building terminals help reduce this cost, but once you make it a HUB, those costs go up again (still cheaper than if you do just gates).
