Hi all,

Thanks for the kind comments, and thanks to CheeseToastie for a few data sources (UK APD & a method for calculating the distance between airports).

As a result I've updated the tool to include a UK Air Passenger Duty calculation and miles between airports (you never know, it might help you work out the longest leg for some reason....)

I've also put in the following fixes;
  • Taxes only included the first 5 flights - Now counts all 10
  • The credit card payment was double counting with multiple passengers in some scenarios - tweaked the formula

Based on the comments around the Mac being slow (I can't test as I don't have one) I'd recommend;
  • - Change the cell saying 'Calculate costs as you go along' to "No"
  • - Complete all your flights etc
  • - Manually run the (new in version 0.2) Macro called RunManualCalculation - not sure if it will work or not, I don't have a Mac to test.

In my own view there are too many different factors (key being seat availability - but also the airline quality, taxes, cost in BD miles, distance, flight connections) to consider - whilst it would be feasible (with quite a lot of coding) I think you'd get much better feedback on the board by asking, rather than using an Excel calculator so I won't be spending the time adding this at the moment.

And everyone is right, it would be much better on the web, sadly I've no web hosting (or desire to get) and this was only a bit of a refresher course in Excel for me - not a web programming exercise . Feel free to develop one of your own, and you're quite welcome to reuse my code too - happy to help with that but sure it would be simple to do with PHP & MySQL.
