Prior to applying to and interviewing for this role as an Airline Customer Service Agent, it is important to know that both the TSA and FAA have strict regulations for background checks for airline staff. They require commercial airlines to run criminal background checks on prospective employees, and there is a specific list of criminal activities that can automatically disqualify your candidacy for the job. As well, they do require that an employment verification check does take place as well, where the airline will look into at least the last 10 years of your employment history. At this point in your interview, you need to be open and honest about any gaps in employment that you have and any blemishes that you have on your criminal record. Keep in mind, you should explain any gaps in employment with a legitimate reason, and you should address anything on your criminal record, even if it is something as small as a simple speeding violation in a vehicle.
