Prior to even applying for the job, it is important that you read the Ticket Agent job posting that you will be interviewing for so that you have a really strong understanding of the physical demands of the job. Working as a Ticket Agent requires long hours on your feet, lifting heavy baggage that is being checked, and working into the wee hours of the night. For your answer to this question, be sure your interviewer knows that you fully understand the physical demands of the job and reiterate to them that you are able to handle all demands. Using examples of times you've had similar physical demands during your career will help your interviewer see that you have the physical ability to perform the job.
