When a customer asked for an excel formula of the International air freight. 

Customer: 

I need help with the air freight formula.

I am doing an RFP and want to make sure I get the formula from the template accurately.

Do you have a formula you can share for excel?

Support: 

 We don't have an excel version. The formula is too complex in excel because of the minimum and maximum charges in there.

Customer:

How about a typed out formula?

Support:

I attached a spreadsheet for you. It's the international template with the algorithm explained along with a sample line.
