Vantaggi
You'll learn a ton about the travel industry and the ins and outs of passport/visa processes, will talk to and interact with people from a ton of Fortune 500 companies and media, will definitely find yourself doing a little of everything.
Svantaggi
When management tells someone in an interview they're expected to do 30 files a day, they have no idea how much work that is, especially with followups. NOT a job for people who want to leave work at 6 on the dot. You will find yourself skipping lunches and staying until 8, maybe 9:00 at busy times of year, and then being told overtime is not approved. Customers are not understanding. I had someone tell me they wanted to shoot me and it was laughed off. Multiple of us definitely sat crying in the hall at various points. Stress through the roof. They installed cameras behind us to monitor our productivity while I was there. NO hope of career mobility unless someone dies, basically. Oh, and two different people got fired while I was there for taking too long with bereavement.
