One advantage of a conscientious travel agent is their ability to keep tabs on cancelled flights and explore other options for you.

I'd booked a Mandalay-Bhamo flight for November 19 that was cancelled 2 days before departure. Since my travel agent handled the reservation she 1) immediately e-mailed/texted me of the cancellation 2) checked for other travel options and 3) sent me options by November 18.
