It was orderly and peaceful when I boarded my United flight at united airlines terminal chicago ord. To prevent crowding or misunderstanding, the gate officials politely and promptly called boarding groups. They handled everything with a grin and patiently responded to inquiries. It was encouraging to see how they gave families and those in need of more time first priority. It made boarding the plane much more comfortable and was among the most well-organized boarding experiences I've experienced at a large airport.
