During my work career, I did a lot of business travel and always used an agency. Now, as a retiree and with all the available online resources, I’m considering doing all the research and booking myself. Opinion? LJMcC, PhilaPA

A: Of course, you may be able do it yourself. However, if you still travel frequently, remember how your hometown agent helped when you were stuck in the airport because an airline booted you off a flight. Or when you arrived at a hotel and your booked room wasn’t available. Agents are involved daily with the constantly-changing realities of travel, and are available by phone or email 24-7 to help when you need them.
