An Airport Parking Reservation Systems and Techniques survey (“the survey”) was developed to assess the benefits, costs, and operational and financial results of airport online parking reservation systems. The survey was hosted by Steer using Microsoft Forms (Figure B.1).
The remainder of this appendix is divided into the following sections:
Over 25 airport operators were contacted to participate in the survey. A total of 18 airport operators representing 20 airports provided responses, including seven large-hub airports, two medium-hub airports, six small-hub airports, and two non-hub airports. Table B.1 provides a list of respondents to the survey and the applicable airport(s) and associated airport hub types based on U.S. FAA 2023 definitions and enplanement volumes.

The average survey completion time was just under 28 minutes. The following section details the response for each of the 17 individual questions as introduced in the preceding section.
Question 1: Please identify your airport (IATA code) - if you are affiliated with an airport operator that runs multiple airports, please fill in separate entries for each airport.
Question 2: Does your airport offer customers the option to reserve parking products through an online booking system?
As illustrated in Figure B.3, 17 respondents offer customers the option to reserve parking products through an OBS, while one operator respondent reported not having one. This operator previously had an OBS but removed it.
Question 3: If available, what are the costs for equipment and other capital costs associated with the online booking system?
Responses have varied from a fixed annual implementation fee to a per transaction fee. The responses vary depending on how these systems are procured and/or operated and whether other components beyond an OBS were purchased.
For instance, one airport procured this system based on a term agreement with a fixed implementation fee, while another airport purchased its OBS system with other parking and garage improvements.
The following lists the responses received. For commercial sensitivity reasons, vendor names and specifics have been removed in the responses. Provided costs are assumed to be real at the time these airports implemented their OBS.
Question 4: If available, what are the operating expenses for the online booking system for airport and/or contract staff?
Responses varied from a fixed annual fee to a per transaction fee. As per the responses in Question 3, the operating costs vary depending on the scope of the contract with the vendor. For example, some airports procure the OBS as a standalone product, while others have this as part of a broader parking operations contract.
The following lists some responses:
Question 5: What percentage of parking inventory does your airport currently make available through the online booking system? Please provide a percentage breakdown on a per product basis.
Each airport has provided a wide range of responses. Due to commercial sensitivity, detailed responses have not been provided. However, in summary:
Question 6: Does this inventory change over time? For instance, a lower proportion of inventory is made available during peak holiday travel.
Figure B.4 provides a summary of the responses. Most airport operators (15) make changes in parking inventory that is reservable in the online parking reservation system, while two airport operators do not make changes to parking inventory at the time of the survey response.
Question 7: Does your airport parking online booking system offer discounts compared to the “roll-up” or “drive-up” rate?
As illustrated in Figure B.5, 13 airport operators provide discounts (of varying proportions) compared to the drive-up rate, while four airport operators do not provide such discounts.
Question 8: If yes, does your discount vary by the lead time before the departure date?
Of the 13 airports that offer discounts as per Question 7, as illustrated in Figure B.6, 10 of those airports have discounts that vary based on the lead time before the departure date, while three airports have a fixed discount before the departure date.
Question 9: While in the online booking system, does your system offer customers the ability to upgrade to a different parking product?
As shown in Figure B.7, the majority of airport operator respondents push upgrades to different parking products (for instance, from a remote, value-oriented parking product to a terminal garage product). Four airport operators do not push upgrade offers.
Question 10: While in the online booking system, are customers offered other services or offers?
Figure B.8 illustrates the results of this question. Aside from other, four airports offer automobile-related services, such as, but not limited to, cleaning, within the parking reservation system. It does not appear that survey participating airport operators have yet used their parking reservation systems to push other airport services; whereas international airports, such as Vancouver International and Manchester International, offer customers the ability to purchase airport lounge access.
Question 11: Does your airport capture customer data through the online booking system into a customer relationship management (CRM) system?
As illustrated in Figure B.9, 10 surveyed airport operators capture customer data from the airport parking reservation system to a CRM, while seven do not.
Question 12: Is this information used to offer (or push) discounts for future parking?
Among the 10 airport operators that capture customer data into a CRM as per Question 11, as illustrated in Figure B.10, eight of those airport operators surveyed use the information to offer or push discounts for future parking reservations.
Question 13: Is this information used to offer other discounts for airport services?
Among the 10 airport operators that capture customer data into a CRM as per Question 11, as illustrated in Figure B.11, apart from one airport operator, most airport operators have not yet used this information to offer (or push) discounts for other airport services.
Question 14: Do you have data that suggests the online booking system has increased the parking share of customers accessing the airport (for example, as against other modes such as on-demand ride app services)?
As illustrated in Figure B.12, the majority (nine airport operators) of responses do not have data that suggests online booking systems have increased the parking share of customers accessing the airport, while eight have and track for that data.
Question 15: What benefits has the online booking system provided the airport?
Figure B.13 lists the different response choices (multiple selection) and the number of respondents that agreed with the option. Improvements to customer experience appeared to be the benefit that applied across most airport operators. Meanwhile, the majority of airport operators have observed improvements to parking utilization (or occupancy) of parking facilities as a result of a parking OBS, with the same number highlighting that the future demand data is a benefit for the airport. Fewer airport operators (11) noted that the additional customer data is a benefit, and even fewer (seven) noted that airport OBSs have increased revenues compared to pre-OBS integration.
Question 16: Reflecting on the overall experience of purchasing, installing, testing, and using the online booking system, please rate your overall satisfaction on a scale from 1 to 5, where:
As illustrated in Figure B.14, most airport operators were satisfied or very satisfied with their experience purchasing, testing, installing, and using an OBS. Only one airport operator provided a neutral response.
Question 17: Would you be available for additional follow up for the study?
The purpose of this question is to identify potential airport case example candidates and survey clarification, if required. Apart from one airport operator, most airport operators were available for follow up, as illustrated in Figure B.15. Airports that answered “Yes” were considered potential candidates for the Case Example Interview.
