Schedules or American Airlines Manage Reservations aren’t always fixed in stone, and we may need to alter our trip plans at any time. Regrettably, those adjustments frequently come at a cost. Changes can sometimes be made without charge, although this is not always possible. Before purchasing a ticket, do some research on the airline. We are often lulled into taking the lowest option, but if your circumstances change, you may find yourself on the losing end of the bargain. Read the company’s website or ask your travel agent what happens if a flight is cancelled or if you need to adjust your schedule before purchasing your ticket. Knowing this information ahead of time will help you prepare for such a situation.
