Navigation fees

[krazykarl]

Can someone explain to me how navigation fees work?  I have an early on airline that originally ran routes to two citys.  City B was not making a profit so I canceled the slots and moved the aircraft to flying to city A.  Now that time has gone by I see switching citys has costed 2.5mil.  Is that an error or is that the fee for canceling the slots/route?  It was only 3 flights a day that got canceled.

Navigation fees include one time fee like slot purchase and normal fees like landing fee (depends on aircraft weight and size), controlling in the air etc.

What you have payed are slot costs for your airport and the airport you want to fly to. Slots can be very expensive and even they are a one-time fee one should notice where the money goes and think about alternatives - for example flying to a not so expensive destination airport.

curse is 100% correct.    One note to add is that slot costs do increase each time you buy them

i guess the main thing that bewilders me about it is that it cost five times more than the same amount of slots and the same sized aircraft.  im not even talking about heavies here, im running Embraer 195STDs, and only two.  the two airports are KMSP and KDTW.  over all they are bairly more than moderatly populated, most flights by major airlines.  the 2.5 mil just doesnt seem right for the situation, if you know what i mean

The bigger the airport, the more expensive the slots.  Also, airports don't care if you're flying 30 seaters or 300 seaters--a slot is a slot.
