​​​​​​​​​​​When evaluating and determining the overall airport performance, it is crucial to have a balanced view of the system from the perspective of different airport stakeholders and users. Therefore, IATA and ACI have joined forces to provide an objective and unbiased analysis of the Level of Service (LoS) at airport terminal facilities. The joint assessment will determine the best possible solutions to optimize the LoS for the whole airport community.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

Optimize your airport resources!

Where to start?

The first step to optimize airport resources is to know where you stand. Comparing yourself to leading airports and industry standards will allow you to identify areas where you need to improve in order to minimize waiting times, to maximize the efficiency of facility operations and to ensure cost-effective development. The application of the improved Level of Service (LoS) concept, featured in the IATA Airport Development Reference Manual (ADRM), provides a detailed benchmark and determines if:

  • Your airport processes offer optimum passenger waiting times and adequate space.
  • Your airport's infrastructure is optimized for current operations and suitable for future growth.
  • Your CAPEX and OPEX are adequate.
  • The contractual obligations of airport owners, operators and/or third-party service providers are met.

Our services

  • LoS Assessment

Analysis of the LoS within current or future terminal facilities, complemented by recommendations for improvements.

Note: The future LoS can only be assessed by using simulation technology.

  • LoS Planning

By carrying out a comprehensive capacity/demand study, the future terminal facility requirements for all processing / holding / circulation sub-systems will be determined, using the OPTIMUM LoS parameters as key inputs.

  • LoS Training

Coaching on the Improved LoS Concept and its correct application.

  • Modification of existing Service Level Agreements (SLA)

Technical assistance for correctly adjusting old LoS specifications (within concession contracts or SLAs) to the Improved LoS Concept.

  • Expert recommendations from the creators of the LoS Concept

With the ADRM, IATA & ACI define airport industry standards and guidance materials that are commonly recognized and applied globally. The ADRM is the most comprehensive manual for all aspects of airport planning, capacity definition and facilities design. It includes the Level of Service Concept – which is a main criterion for developing passenger terminal facilities or for assessing the provided service performance. IATA & ACI are the originators of the LoS Concept and therefore understand best how to correctly apply it.

  • Comprehensive subject matter expertise

IATA & ACI have played a key role in the aviation industry for decades. During this time, our experts have gained extensive experience in elaborating multiple LoS studies for small regional airports to big international hubs. Our expert team has hands-on knowledge about international airport planning standards & best practices and can effectively adapt the LoS Concept to specific local requirements.

  • Easy stakeholder access and consultation

As the global representative and trade association of the airline and airport industries, IATA & ACI have direct access to their members. Having straightforward access is essential for collecting critical inputs (such as actual processing times, waiting time expectations etc.) when it comes to carrying out LoS studies.

  • Neutral

The evaluation process and recommendations pertaining to LoS will be fair and unbiased – to ensure achieving the best possible solutions for the whole airport community.

  • Essential planning tools

Our experts use advanced planning tools –such as simulation– in order to support all kinds of LoS-related studies. Especially in case the analysis requires the detailed assessment of future facility requirements or when terminal operations have major implications, a dynamic simulation tool is essential to derive precise results.

Below is a selection of some of our clients:

Consulting_LoS_Ositran

OSITRAN, Peru / Independent LoS Assessment for 15 airports

Commissioned by a Peruvian governmental entity supervising public transport infrastructure, IATA conducted a detailed Level of Service Assessment study for 15 airports that are being operated by private companies. Over a study period of 180 days, all airports were inspected during their typical busy periods and all relevant LoS KPIs were measured on-site (e.g. actual waiting times, queuing lengths and queuing space), at the various terminal sub-systems. Upon completion of data collection, a thorough LoS analysis has been carried out, following IATA’s best practice methodology, the guidance from IATA’s Airport Development Reference Manual (ADRM) as well as the agreed, specific LoS requirements/targets as outlined in the airport concession contracts. At the end of the study, IATA presented to OSITRAN the final results, consisting of each airport’s LoS performance for the reference year 2019.

 

 

 

 

 

 

(LED) St. Petersburg International Airport / Terminal 1 / Independent LoS Assessment (sophisticated approach)

IATA first performed a comprehensive baseline simulation on a typical busy day to understand the current situation in terms of terminal capacity & service levels at the various sub-systems. IATA then organized an expert workshop with all relevant airport stakeholders to discuss the baseline results and to jointly develop Quick Win Improvements (e.g. enhancing operational processes, using more automation). Subsequently, IATA performed another simulation analysis to assess the future expected LoS, taking into account not only the assumed improvements, but also increased passenger demand.

 

 

 

 

 

(KUL) Kuala Lumpur International Airport / Terminal 1 / Independent LoS Assessment (sophisticated approach)

After having performed a LoS Assessment for the current situation at the various sub-systems (with support from a simulation tool), IATA conducted an airport stakeholder workshop to converse about the LoS performance and to jointly derive Quick Win Improvements, with the focus on sub-systems that currently do not achieve LoS OPTIMUM. Then, another simulation analysis has been carried out to anticipate the future LoS performance (assuming increased passenger demand), basically to verify whether the proposed Quick-Win optimizations will be effective and resulting in LoS improvements.

 

 

 

 

 

(UIO) Quito International Airport / Main Terminal / Independent LoS Assessment (sophisticated approach)

Once the simulation model had been calibrated, IATA conducted a comprehensive baseline simulation to understand the LoS situation at the various sub-systems. On special request, this LoS Assessment was analyzed for the typical busy days of 6 individual months from the reference year. Subsequently, IATA organized an airport stakeholder workshop to discuss the LoS results and to commonly elaborate Quick Wins, such as enhancing operational processes or using more automation.

 

 

 

 

 

(ATH) Athens International Airport / Main Terminal / Independent LoS / Capacity Assessment (sophisticated approach)

In order to derive precise LoS Assessment results, IATA first build up a simulation model and calibrated it. Then, a comprehensive baseline simulation on a typical busy day has been carried out, to better understand the current situation in terms of terminal capacity & service levels at the various sub-systems. Thereafter, IATA performed another simulation analysis to eventually determine the actual terminal capacity, considering certain operational improvements and already planned expansion measures.

 

 

 

 

 

(CGK) Jakarta International Airport / Terminal 3 / Independent LoS Assessment (simplified approach)

IATA first conducted on-site LoS KPIs measurements and observations during a typical busy period, not only allowing the expert team to better understand the current situation and operations, but also to conduct the LoS analysis and eventually determine the LoS performance at the various sub-systems. Afterwards, IATA organized a workshop with the Client (airport operator) to discuss the LoS Assessment results and to jointly develop Quick Wins that can be easily implemented – both in short time and at low cost.

 

 

 

 

 

(AMM) Amman International Airport / Main Terminal / Independent LoS Assessment (simplified approach)

At the beginning of the study, IATA came on-site during a typical busy period in order to conduct LoS KPIs measurements (maximum waiting times & maximum queuing lengths) and observations about the terminal configuration and its operations. The measurements have then been used in the technical LoS analysis to determine the actual LoS performance at the various sub-systems. For sub-optimum facilities, IATA then provided a set of suggested Quick Win Improvements.

 

 

 

 

 

(PVG) Shanghai Pudong International Airport / Terminal 1+2 / Independent LoS Assessment (simplified approach)

To familiarize with the terminal and its operations, IATA came on-site during a typical busy period. This inspection was also used to measure the actual LoS KPIs during the peaks. Then, this captured data has then been used as key input to the LoS analysis and subsequent determination of the LoS performance for each sub-system. After understanding the current LoS situation, IATA organized a workshop with the Client (airport operator) to elaborate on the LoS Assessment results and to discuss about potential recommendations for improvements.
