What do you lot think of a system whereby each seat on an aircraft (regardless of if it is filled) costs x when landing at an airport in a relaxed world? I also think that if this was used then airlines should be able to pre-purchase y seats for a lower per seat price.

How would pricing be calculated?

Hadn't got that far yet, was just throwing this in as a suggestion of a way to calculate slot prices.

How about this:
( .01(airport_daily_pax) ) / num_of_seats

But then a bigger plane will cost less. I do though agree that a bustier airport should cost more.

Ok, then here's one:
y=1+(.0001x)^2 {x<=0} (where y=price per seat and x=daily passengers of airport.
and http://desmos.com/calculator if you want to tweak some aspects of the formula.

I typed the formula into the website and got a strange surprise:
https://www.desmos.com/calculator/y6zha6lif6
My problem with this is for busy airports the price is alot! Heathrow has 73,405,330 passengers a year. Routeing this to 73,000,000 still results in a price per seat of £53,000,000!!
[hr]
Also that is a very steep function. I feel that the difference between 19 and 20 seats should be more then between 750 and 751 seats, this is the opposite on this function. Also if you don't like desmos:

[hr]
Also just found this to help come up with a formula, havnt got time to do one now but for comparative data.
Salzburg: 767, $3,800
Dublin: 767, $4,100
Bristol: 767, $4,400
Tokyo (Narita): 767, $5,600
Tokyo (Haneda): 767, $6,850
Sourced: http://www.therichest.com/luxury/most-expensive/10-most-expensive-airports-to-land-your-plane/ - other airports are listed but data is useless as the lane type isnt stated.
[hr]
edit: also came across http://www.miami-airport.com/pdfdoc/Fees_and_Charges_Book.pdf. Very complicated but the jist of it is that on page 8 the cost of offloading 1 average passenger at Miami airports was $20.14 (including charges for things like security)for the financial year 2014-15. The breakdown also explains on page 13 that of this the cost of landing a plane per 1,000lb for the same period was $1.58. Document is very useful for other things (also has parking fees- P15) which you can find if you read the document in detail.
[hr]
Just gone a bit further - if you look at P18< lots of excellent data broken down into aircraft type! Only problem with purely relying on this is that we don't have any way to extrapolate data if we only look at one airport.

Summery of Miami airport document if you cannot handle all of that information:

A1—Bus $7.00 per trip
A2—Van $3.00 per trip
A3—Limo $3.00 per trip

1st, the function was daily passengers (for LHR 200,000), so the price comes up to the still too expensive $401/seat.
2nd, wow, that's a lot of data!
3rd, based on that info here's a new formula:
y=10+.0000005a|b-sqrt(b)|, where a is daily pax of airport and b is total seats on plane.
So, at MIA (Daily Pax: ~112,500), a B744 (660 pax) would cost $46/seat, while a Short 330 (30 pax) would cost $11/seat.
While at LHR (Daily Pax: ~200,000), a B744 (660 pax) would cost $68/seat, while a Short 330 (30 pax) would cost $12/seat.
And at ATH, (Daily Pax: ~41,500), a B744 (660 pax) would cost $23/seat, while a Short 330 (30 pax) would cost $11/seat.
