Busy and confusing. It's a nice and large open space filled with many escalators and walking escalators. The people are friendly and do try their best to help. Every terminal/section has a special desk where people who have missed their flights can go to rebook and/or get on standby flights. Unfortunately, the customer service desks cannot handle situations where there is a large number of people who need help. The lines can get absolutely ridiculous!! \n\nOverall, a relatively comfortable area (for an airport) with plenty of food options.
