Hello, According to my cousin’s experience, the visit to the united airlines corporate office in Chicago was smooth and professional. The office, situated in the famous Willis Tower, was easy to locate and provided a secure and inviting atmosphere. She was treated with respect by the staff, who provided her with the necessary information in an efficient manner. She was struck by the facility’s modernity and the effectiveness of its organization. All in all, it provided her with a favorable impression of United’s corporate culture.
