Flight attendant seniority list.
If you have ever worked for an airline, then you probably already know that seniority is everything. There's not that many company where the date of hire is a big deal, but it is a huge deal when working for an airline. It literally affects your life.
Some people who work for an airline and have a seniority number don't want to try another job outside the airline because if they were to come back to the airlines, they would have to start over at the bottom. So for most people who leave the airlines, there is no going back just to be at the bottom again.
Seniority is a big deal for people working for an airline and especially for pilots and flight attendants. Bidding for schedule and getting the schedule that you want is based on your seniority. If you are low on the list, then you typically get the worst lines or trips that no one else wanted. Those on the top of the seniority list may get twenty days off a month while those at the very bottom only get nine. The top will get the days off they want and the nice trips while the people on the bottom will get the left over trips with days off all over the place.
It takes a long time to gain seniority, sometimes years, but eventually with time your schedule will get better. As it slowly gets better, you will enjoy getting better trips and more days off.
Seniority is also a factor when traveling as a non-rev. This is when when you get to use your airline perk and fly for free on stand by. However, not only are you on standby for an empty seat on a flight, you are also put on a list according to seniority. Not all airlines use seniority when it comes to non-rev travel as some are first come first serve, like American Airlines. But for majority of the airlines, your travel and getting an empty seat is based on your seniority, which is your hire date. So depending on how many non-revs are on standby on the flight, your chance might be good or bad. Just make sure to choose flights that are wide open.
