149th Slot Conference

Rome, Italy
16 - 19 November
Rome Marriott Park Hotel

The Slot Conference (SC) is a "Working Conference". Regularly attracting over 230 airlines and representatives of over 85 schedules-facilitated or fully coordinated airports this twice-yearly meeting is one of IATA's largest events.

The conference operating procedures are published in the Worldwide Airport Slot Guidelines (WASG).


To see the organizations that have already registered please see the registration list (pdf)!

To provide flexibility, the 149th Slot Conference will be a hybrid edition. For those who can travel, we will be delighted to welcome them in Rome, Italy. For those who cannot join us in-person, they will be able to link virtually using the same virtual conference system we used for SC147 & SC148. All attendees will be able to participate in live discussion and program sessions, network with delegates, exhibitors & sponsors and plan their meeting schedule and meet face to face (in person or via the video conference system). 

Whether attending in-person or remotely all attendees will have many opportunities to connect during the conference and we look forward to welcoming you soon!

This event requires registration. Invitations to register for SC149 in-person or virtually were sent to all accredited delegates 09 September 2021.  


It is the responsibility of the Head Delegate of each organization to make sure their delegation is up to date as only delegates accredited in the Online Accreditation System can be invited to register for the conference. If you have not received an invitation please check with the Head Delegate of your organization that you are accredited, if not they should do this. We have created a help page for OAS with more information. If you are accredited in OAS and have not received an invitation to register by the time that registration opens please contact the registration team directly at IATASC@MCVEIGH.COM.

To ensure you receive your invitation to register for future events, please take a moment to save IATASC@MCVEIGH.COM to your email Safe List. This will ensure you receive your invitations and they are not filtered by your organization's email system to your Junk Mail folder.

We recommended delegates speak with their IT dept. to ensure IATASC@MCVEIGH.com is saved to their Internet service provider's 'whitelist' and if necessary provide them with the following IP addresses and that are used to send delegates registration emails. This should ensure messages that are sent automatically from the registration system are not blocked by your organization's system.

The 149th Slot Conference will be facilitated in person and virtually using the same virtual conference system as for SC147 & SC148. We’ve collected practical information around the Hybrid Slot Conference below to help you plan your conference attendance.

Accreditation remains necessary and will ensure that only accredited delegates, authorized to complete slot transactions on behalf of their organization can attend and work at the conference. Visitors, Observers and Support staff will be able to view presentations but not attend coordination meetings, as usual.

Attending in Person

There are many great reasons to plan to attend this November’s Slot Conference in person.  While we are busy preparing for the event, we also understand that travel restrictions remain unpredictable, so we will be fully supporting working virtually as well.  But, for many, it’s exciting to finally get back to an in-person event. Here are four reasons why attending the 149th Slot Conference onsite in Rome, Italy 16 – 19th November 2021 will help you to optimize your schedule, while supporting your business partners and colleagues, whether they are attending in person or virtually. 

Health and Safety

IATA's number one priority is the health and safety of our conference attendees, employees and staff supporting the conference.  In partnership with the Rome Park Marriot Hotel, we will adhere to all official government and local authority guidance, as well as any venue or location-specific regulations. Please take the time to read through the following information regarding the Health and Safety protocols (pdf) in place for 149th Slot Conference. As the local situation evolves this information will be regularly updated, in line with best practices.


Currently all attendees are required to meet the requirements of the Italian 'green pass' to take part in the event - more information on this can be found in our travel restrictions guide (pdf).

Travel and local restrictions

We will be closely monitoring travel and local restrictions.  As the situation evolves this information will be regularly updated and we will make sure we inform all delegates in good time if we are unable to hold this event in person.  Please refer to our guide containing official information and government links for travel to and from Italy and local restrictions (pdf). Delegates are reminded that it is their individual responsibility to ensure they meet the requirements for entry to Italy. 

Hybrid Slot Conference specifications

Time Zone

To give the conference an official format we will use the local time in Rome, Italy (UTC+1). 07:00 – 19:00 UTC as core hours for planning of presentations and meetings. These will start at the most convenient time for all attendees and ensure there are playback opportunities for time zones outside of these hours. SPECIAL NOTE for in-person attendees: Make sure you set your time zone to the conference local time before setting your availability, to ensure meetings are requested and accepted in the correct time zone.


Whilst there are delegates attending this conference virtually, the system will be available for use and for making appointments 24 hours a day, to ensure each user in each time zone can block their schedule to the times that they are available and wish to work. This will give you the freedom to make your appointments at the most convenient time for you and your colleagues, in whatever time zone you are present or choose to work in.

For example, an organization may wish to register delegates and roster their staff to concentrate on specific time zones to make best use of their meetings.  One person might be assigned to handle appointments for Asia and Oceana, one for Europe, Middle East and Africa and one for the Americas – this way they could each stay in the relevant time zone and work on getting the results they need in that area.  Others may wish to work more flexibly, when and how it suits them.  You are in control of how you wish to work.  Users will be requested to block the times they are unavailable for meetings during the customization phase of the virtual platform beginning 27 October 2021 at 10:00 UTC.

The Slot Conference Virtual Platform

We have created a help page for the virtual Slot Conference system. The help pages include user guides, videos and detailed instructions and we recommend all delegates to take advantage of the help pages to get the most out of the virtual platform. 


The virtual system opens to all registered participants for customization on 27 October 2021 (10:00 UTC). 

The virtual platform we are using is easy to access online and does not require any plug-ins or downloads, only a good internet connection and a webcam for virtual meetings. From feedback requesting longer timings for these virtual meetings, we have set meeting times to 20 minutes allowing three meetings an hour over the four days.





Program Highlights

We've published a selection of program highlights (pdf), with more interesting and relevant session coming up closer to the event! We'll add more sessions on this page as they are confirmed and we recommend you to check in regularly to see what's new and to start planning your conference.

We have also published the Work rooms and floor plans guide (pdf) to help you plan your meetings.

Please note, that when you sign up for a program session in Swapcard it will not automatically block your availatbility. If you want to ensure that you don't double-book yourself you will need to block your availability manually. For more information on how to do this please visit the help pages

Don't forget that all sessions from the 148th Slot Conference are still accessible on the SC148 event page!

Coming soon!

Airport Slot Coordination Training

Widen your expertise and participate in one of our training courses! We offer two courses focusing on airport slots, the Airport Slots and Coordination course and our new course, Airport Slot Coordination: Policy and Implementation. You can attend both slots training courses also as virtual classroom courses.

Airport Slots Management and Coordination

Airport Slots Coordination: Policy and Regulation (NEW!)

Due to the growth of air traffic’, some airports are experiencing a discrepancy between available airport capacity and demand. Coordination involves the allocation of constrained or limited airport capacity to airlines and other aircraft operators to ensure a viable airport and air transport operation. Coordination is also a process to maximize the efficient use of airport infrastructure. This course will help you learn how to allocate and coordinate airport slots by applying the Worldwide Airport Slot Guidelines (WASG), the accepted global standard for airport slot allocation.

What you will learn

  • Allocate slots according to the requirements and procedures for either facilitated (level 2) airports or coordinated (level 3) airports
  • Apply the standard procedures for communication between airlines and slot coordinators
  • Maximize your slot portfolio management capabilities
  • Apply slot procedures and understand the impact of international rules and regulations
  • Execute slot messages in compliance with SSIM Chapter 6
  • Analyze capacity constraints and historic slot eligibility

See course page for more information and registration!

The aviation industry faces enormous challenges as a result of insufficient airport infrastructure across the globe. The Worldwide Airport Slot Guidelines (WASG) help the industry to meet ever-growing consumer demand for such infrastructure. The Airport Slot Coordination: Policy and Regulation course will provide you with an enhanced and balanced understanding of these challenges as well as the principles that have been developed to meet demand in a fair, transparent, and neutral way while promoting the most efficient use of scarce airport capacity.

What you will learn

  • Describe the global context of schedule planning in a constrained airport environment and how it relates to connectivity, competition, and consumer benefits of aviation
  • Explain the challenges posed by insufficient airport infrastructure
  • Detail the principles and objectives of the Worldwide Airport Slot Guidelines Justify the need for transparency, flexibility, sustainability, certainty, and consistency in airport capacity allocation
  • Advocate for the optimization of scarce airport capacity

See course page for more information and registration!


These courses are available at IATA Training Centers, regional training partner locations, and on-demand as in-company training

Testimonials ​for the Airport Slots and Coordination Course


Adam Mohamed - IOC Senior Operations Controller - Gulf Air

Gulf AirI attended the 3 day’s Airport slots and coordination classroom course to further expand my knowledge in the aviation field. I did anticipate difficulties in completing this course especially in such a short timeframe. However, the instructor taught in such a way the information was passed clearly, whereby we not only understood the content but were also able to apply this knowledge beneficially upon returning to duty.
I would recommend from my personal experience this course for anyone in the aviation Industry.​

Liva Ozolina - Scheduling and Slot Manager - AirBaltic

Air BalticEven though I have been working with slot handling messages and WSG for few years now, this course was very useful for strengthening my knowledge and for learning new specific details with well though examples on respective cases. I would suggest this course for everyone whose daily work is related to airport slots.​

​Md Ashraful Haque - Manager Operations-Schedules Planning - Biman Bangladesh Airlines

Biman Bangladesh AirlinesThough I had some previous hands-on experience on Airport Slots and Coordination procedures but in some critical cases I experienced some situations when it would get very difficult for me to find a solution. A sincere thanks to IATA for arranging such an advantageous course, which gives a clear idea about ins and outs of the airport slot coordination.
The course covers a wide range of information about scheduling guidelines and slot handling procedures.
