Thread: Fees & Taxes - How To Figure 'em

We're planning a trip that will take us around the world (mostly because Cathay and Scandinavian ZED's are temporarily suspended for our airline). In order to do this, it's starting to look like we've developed an extensive routing matrix. While I can ask for a quote from my travel office (USAIR), it's going to be a fairly large list of city pairs, and I'm wondering whether there is a way to grab the information off of the various airline websites as they provide a broken down listing of taxes/fees for each flight that is sold to "real passengers".

Can anyone tell me which specific fees/taxes are always added to ZED fares, and which are never added to a ZED ticket? Years ago, I wouldn't have worried about it too much as these fees and taxes were usually always trivial. That is no longer true, as anyone who has flown out of LHR can attest. On many occasions, the fees and taxes can be multiples of the actual ZED fare. Is there an automated method of determining these numbers without approaching the Travel Office? I truly don't like bothering them if there is some way for me to come up with the numbers on my own.
