Selling Value of Premium Passes

I have added a section in the airport rewards sheet in the Airport and Aircraft Information spreadsheet. 

Here is the ranking of the selling value of transferrable airplanes in the premium pass per GP, measured in Wollars per GP. You can use this list to see the best premium passes for preparing for the next airport, since you can sell transferrable airplanes at other airports for a jumpstart. This will be compared to the value of GP purchases.

1. SXM - 36990

2. NGO - 32520

3. SAN - 22545

4. PRG - 20748

5. BKK - 17089

6. MSY - 15879

7. MCT - 14955

8. BRI - 14783

9. LEJ - 13838

10. LHR - 12600

11. INN - 12210

12. 100 GP for 1.2M wollars - 12000

13. 50 GP for 600k wollars - 12000

14. IAD - 11651

15. 25 GP for 280k wollars - 11200

16. 10 GP for 110k wollars - 11000

17. GRU - 10508

18. 1 GP for 10k wollars - 10000

19. SYD - 9630

Buying premium passes at finished airports and selling transferrable fleet planes is better than exchanging GP for wollars. The top 4 airports all require 30 GP or less (SXM costs 20 GP), but they allow a substantial amount of wollars to be earned from selling transferrable planes - the GP-to-wollar exchanges are twice or three times as expensive to get the same amount of money.
