Pros
It's a job. Worked at the corporate office, I had fun and liked the people who worked there. I know not everyone had the same experience. Working in different departments was a good resume builder. Traveling was a great time.
Cons
Not much if any upward mobility, some of the management staff are clueless. They do not pay competitively for some "management" positions but all the stress and pressure. In my experience, I did many different jobs and was always going the extra mile and there was really no recognition. Lots of turn around in the TA and Reservations Department. Also, I did not work in Reservations but wow... even if you call in sick once you loose half of your commission. No matter if you were terribly ill or your child was. Even if you had sick days banked and are a full time employee.
