Ted,
I'm not from the USA, but i hear about a lot of ticket misrepresentation going on there. The only way you will find out the true cost, is to call the agency and ask them for a total cost on that ticket. CS shark advises to purchase tickets from Chinatown travel agencies, Say's they are always the cheapest in the US.
Our ticket system in the UK has far more controls on ticket advertised pricing than the US, and even we get shafted with the true cost of the ticket at times.
As i say always call the agency direct to get the true cost of the ticket before just sticking it on the card. Normally, if the time allowed allows them to post your ticket on to you, they will do it. If the time allowed is not of sufficient time, you pick the ticket up at the airport, you may have to pay a small charge for that service. They will give you your ticket code number, which you need to give to get your ticket at the airport. So you give your name and the code number and they give you your ticket . you may also need the credit card that you purchased the ticket with.....
Hope that's been a little help, if not wait for your fellow yanks to tell you there experiences with airline ticketing
