Sometimes the role of check-in assistant or customer service agent includes walking with passengers to and from the aircraft, arranging facilities for people with disabilities and generally ensuring all passengers are boarding their planes on time. Unlike cabin crew who are travelling great distances in their working lives, airline customer service employees are ground-based and typically work at one airport at a time. Often shift work is required, due to the long operational hours of airports, and part-time work is widespread. Uniforms are likely to be provided for most airline customer service agents.
