Is there an AirLine that lets you fly for free If you work for that airline?

every airline gives you one free fligh/holidayt a year ( other than the flights you work on ) plus free accomodation while you work for larger stop overs

If you are a cabin crew you are most likely to fly free at least once a year. It really depends on the company's policy though. Some airlines also offer free or discounted (90% off) flights for immediate family members. Again, depends on the company, your free flight may be on a stand-by basis.

Most airlines give you pass travel benefits which are either free or close to it. However you fly stand by so you can never be sure you are going to get on.

yup, one airline that i know have this benefit to all of its employees as long as you have stayed with the company for 1 year...the employee gets unlimited domestic travel trips but limited international flights... limited flights are also applied to immediate family members...

Qatar airways offers free flight benefits as part of their package if you ever got a chance to work as a cabin crew or flight crew.

all of them every day when you go to work!!

that all depends on what your working as... steward/stewardess: yes
pilot: hell yes plus immediate family fly for free too
as for smaller positons, im not that sure but i am pretty sure that you will get a discount for a flight..
most airlines do this
hope that helps
