I have been looking a variety of threads here but have not been able to figure out how to determine what the actual surcharge amounts are. I frequently fly Omaha-Hanover (OMA-HAJ). Using Krisflyer miles is an interesting new option for me. I am interesting in economy mostly as I will be flying a number of family members back and forth next year. I found that Krisflyer charges around $200 one way using a SQ flight (when looking for ORD-FRA). Lufthansa using Miles and More miles charges even more sometimes. United changes no fuel surcharge. Is there a way to check how much Krisflyer actually charges when booking a UA or LH flight without actually having any Krisflyer miles yet?

If not, can I get some data points for econ tickets, please?
