At issue is the extraordinary number of flights scheduled for O’Hare this summer. For example, United Airlines said it planned to operate roughly 780 flights per day from O’Hare, which would be a dramatic increase of about 200 daily flights and would lead to a schedule that would exceed airport capacity during the peak times.

Left unresolved, it could create significant travel disruptions in the near term — just in time for the peak summer season — and higher prices and fewer services in the long term.

The airline wants to crowd out American Airlines and reduce competition, and the FAA is stepping in. This is one of many problems facing travelers that Congress should address.
