We use a TA when it comes to flights. I drive to WDW with our camper and dog. Wife and sometimes kids fly in later. Yes I can find flights online and sometimes I tell the agent what I have found, but if something goes wrong, weather or mechanical delays, I want someone to help me get things back on track while I'm not there. Sometimes I'll find a cheap flight and then the agent says you don't want to fly that airline, hidden fees, bad online times. I feel safer with someone that knows the ins and outs of air travel. I make my own campsite, ADR's, and fast passes.
