How to read this page

The destinations table is the core of an airport profile. It tells you, at a glance, where you can fly directly from UIO on a published schedule. The "operators" column doesn't measure frequency. It measures how many distinct airline codes file the route. So a "3" means three different carriers list UIO to that destination, even if one of them runs the route many times a day while the others only manage it weekly. For practical trip planning, use the table as a starting list and confirm the airline's own schedule for your travel dates.

The airline list shows which carriers treat UIO as part of their network. Many will be foreign carriers running one or two flights, while a handful will use the airport as a base.
