if you want to avoid the hassles of what traveling is like right now. Do what works for you, and not every travel agent is going to be great.
Just saying, I know what my wife does for her clients--and I'd much rather do a thousand other things than waiting on the phone or having to deal with travel vendors who are almost all undermanned right now.
The current environment of travel is crazy right now, do you want to deal with it all or would you rather have someone who is used to dealing with it for you?
