Baggage handler
In the airline industry, a baggage handler is a person who loads and unloads baggage ( suitcases or luggage), and other cargo (airfreight, mail, counter-to-counter packages) for transport via aircraft. With most airlines, the formal job title is "fleet service agent/clerk", though the position is commonly known amongst airline employees as a "ramp agent", due to the job's location on the airport ramp (tarmac).
