I almost always use the same travel agent; I'm fortunate enough to have found a good T/A who meets my needs and often saves me money (especially on hotels) compared with what I find on my own, knows my desires for mileage-run routings and automatically searches for them when booking my flights, and keeps up to date about my preferred leisure desinations and calls or e-mails me when there's a good fare available to one of them in case I want to take advantage of it.
And, as someone else also said earlier, mine has become a friend.
But as some other someone else also said earlier, it's a business with no future and Ann has returned to school and is studying to become a CPA. When she's out of the business I'll probably do most of my own bookings until and unless I can find another agent who does her job as well.
