Warning!

The slot availability displays only show runway slot availability. Other constraints, such as terminal or stand capacity or night period restrictions, may prevent slots being allocated as requested. The aircraft operator is responsible for complying with any and all additional restrictions or conditions that may apply to the operation of a flight at the airport concerned and must check the relevant publications (eg, NOTAMs, the Airport’s Conditions of Use, etc).

The allocation of a slot does not imply the availability of all facilities necessary for the operation. In all cases it is the aircraft operator’s responsibility to make suitable ground handling arrangements.

Merge Totals (recommended)

To see the runway slot availability for adding a new flight, ALWAYS select merged totals.

Most airports have a limit on the total number of runway slots and sub-limits on the number of arrivals and departures, eg, up to 40 movements per hour in total, of which up to 25 can be departures and 25 can be arrivals.

If an hour already has 14 arrival flights and 25 departure flights (39 in total – only 1 runway slot available), with merge totals selected the availability will be 1 arrival and 0 departures. This is the true availability for adding a new flight.

Without merge totals selected, the runway slot availability will be 11 arrivals, 0 departures, and 1 total slot. This means that an existing departure may be converted into an arrival, but not an arrival into a departure. Use this to test for possible arrival/departure slot swaps.

Detail View


The Week, Season by Day-of-Operation, and Season by Time views give the hourly runway slot availability.
To see the availability at a specific time within an hour, click on the appropriate cell to see the Detail View.

Note, the detailed availability is shown even if the hourly capacity is full. This is useful if you are trying to move a slot within the hour, say from 0910 to 0915.

Also, the runway slot availability is shown for each 5-minute period even though the constraint may be a 10 or 15-minute limit.

For example, if there is a 15-minute limit with 1 slot available between 0900-0910 then the time periods 0900, 0905, 0910 will each show 1 slot available. This means that a slot is available at 0900 or 0905 or 0910, not that 3 slots are available between 0900-0910.
