To calculate taxes, double click on the desired Fare in the KVS Tool and select [Find Flights Using This Fare].
Every time I do it on the flights to Europe (Same-Day Turn-Around/MR) I get this: No Trips Found. No flight options were found for the first segment of this trip.
What am I doing wrong? I'm doing DCA-FRA or DCA-LHR and every single time I have the same message on ita.
