Northern Winter 2020 – HBD Guidance for Airlines

As Covid-19 continues to impact the aviation sector, there remains a great deal of uncertainty surrounding waivers from the utilisation target. This may lead to unintended consequences if returning slots without first considering if a waiver is in place. The following provides details of the current situation at ACL airports as at 26 August 2020.

Historic Baseline Date (HBD)

The HBD remains 31 August 2020 and ACL will create the results table which determines the utilisation target for each slot during NW20 on or shortly after that date.

Waivers as at 26 August 2020

Waivers are currently in place for ACL airports in New Zealand and Dubai covering the entire NW20 season. Alleviation will be granted subject to certain conditions which are detailed here. This document will be amended as information changes.

A waiver is not currently in place for any of ACL EU & UK airports so cancellations made will be treated as per the EU Slot Regulation as would be the case in any other season. Carriers are encouraged to consider the below information when determining when to make cancellations at these airports.

Cancellation before the HBD

Carriers wishing to benefit from the 20% cancellation allowed before the HBD should continue to make these changes as normal. The cancellations will be included in the calculation of the utilisation targets. Details of how ACL determine historics can be found at the following links:

London Heathrow

Other (Northern Hemisphere) ACL Airports

Additional Information for Dubai International Airport

Cancellations more than the permitted 20% may result in the returned slots being made available to other carriers which may impact on your ability to retain the historic. For examples full season cancellations made at this time will be returned to the slot pool and reallocated.

Cancellation after the HBD

Airports with a waiver (New Zealand & Dubai)

At airports where a waiver is in place, alleviation will be granted to cancellations made after HBD subject to any conditions in place. Cancellations meeting the conditions will be counted as operated against the utilisation target.

Airports without a waiver (ACL EU & UK Airports)

Any cancellation made after the HBD but prior to a waiver being issued may not count towards the utilisation target and may impact on your ability to retain the historic slot. For example, a full season slot returned after the HBD but before any alleviation has been granted will be returned to the slot pool and reallocated.

Carriers will need to make their own assessment on the timing and likelihood of a waiver and determine their hand back strategy accordingly.

If alleviation is granted, cancellations made after the waiver announcement will be treated as operated subject to any conditions in place.

Newly Allocated Slots

ACL issues all newly allocated slots on a non-historic basis. ACL will consider newly allocated slots should they operate in line with 8.7.1(d) of the WASG. ACL has prepared Guidance on how newly allocated slots will be treated which can be found here.

Carriers not intending to operate newly allocated slots are requested to return these as soon as possible.
