ACL Update on the Middle East Conflict

1st April 2026 

Operations in the Middle East region remain severely impacted.

ACL has published Guidance on Military action and related airspace restrictions over the Middle East and Gulf Region – see here for the latest version (6).

For Dubai Airports:

  • The schedule has been deleted until 31st May Capacity continues to be extremely limited. Manual slot coordination is in effect. Airlines are requested to submit requirements to ACL at slots@acl-international.comor via OCS.

For Abu Dhabi:

  • Airlines should contact the airport directly with any enquiries relating to operations in S26 until advised otherwise.

For Oman airports:

  • In Muscat, the airport has advised that any additional flights require prior approval, and all repatriation flights must have their slots obtained through the handling agent (Transom).
  • Duqm, Suhar and Salalah are operating as normal.

For Saudi Arabia airports:

  • The airspace remains open and commercial flight operations continue. For repatriation flight requests, additional approval from the Saudi authorities is required before slots will be confirmed.
  • There are adjusted day-to-day processes now in place across certain Saudi Airports for the coordination of short-notice ad-hoc flights as follows:
  • Al-Ahsa (HOF), Al-Qaisumah (AQI), Damman (DMM): All slot requests for non-based carriers should be submitted in linked Arr-Dep SCR format. Unlinked (Arr only or Dep only) slot requests will be rejected, Some requests may require a referral to the airport and may take longer than usual to respond.
  • All other Saudi Airports continue with their normal day-to-day processes.

Please contact the applicable ACL team for more information.

Northern Summer 2021 (NS21) WASB Slot Waiver Announcement

The Worldwide Airport Slot Board (WASB) issued its recommendation for airport slot alleviation measures covering the Northern Summer 2021 scheduling season. The following provides some initial guidance to give clarity on its application at airports coordinated by ACL to avoid unintended consequences should airlines apply the WASB recommendation immediately.

VALIDITY

The WASB announcement is a recommendation. For a waiver to be applied, the Regulatory or competent authority needs to adopt this recommendation or issue an alternative waiver. Across all ACL airports this has not yet occurred so currently NO waiver for Northern Summer 2021 is being applied.

When the position changes, ACL will update its guidance.

CANCELLATIONS IN ADVANCE OF A WAIVER

Any cancellation made prior to a waiver being issued may impact on your ability to retain the historic slot. For example, a full season slot returned before alleviation has been granted will be returned to the slot pool and reallocated based on the waitlist at that time.

FURTHER GUIDANCE

Once ACL is aware of the detail of any formal waivers, it will review and where necessary provide further guidance. The current guidance on alleviation can be found here.
