Most positions advertised by United Airlines are very team-oriented. So, spend time examining their brand of teamwork and performing adequate research on yourself to determine how aligned you are. They define a team player as someone with a "consistent track record of working independently as well as a part of the team." United Airlines defines teamwork as "working well in a collaborative setting, supporting work team by volunteering for and completing assignments, acting as a positive team member by contributing to discussions, developing and maintaining both formal and informal relationships enterprise-wide, defines success in terms of the entire team through mentoring and knowledge transfer." When answering this question, you don't want to repeat their definition of teamwork, but rather consider how you would say the same with sincerity in your own words.
