Event registration software.Forms, RSVPs, plus-ones.
AirLST is event registration software that builds the registration form your event needs, with plus-ones, workshop sessions, travel and hotel included. Every RSVP goes straight into the guest list, capacity limits update in real time, and the confirmation goes out with a ticket.
We make event registration smart.
Standard fields plus anything your event needs, with required fields and conditions.
No form export, no retyping: hitting submit adds the guest to the list.
Per event, guest group and workshop session; full means waitlist, not overbooking.
Email with ticket, calendar file and a personal link to make changes, right after submitting.
An event registration form that asks what your event needs to know.
Standard fields from salutation to phone are built in. Add travel details, workshop sessions, side events, hotel, dietary needs and custom fields in the editor, with required fields and conditions: the flight number only appears when someone is flying in.

Salutation, title, first and last name, company, department, job title, address, email, phone.
Workshop sessions, side events, arrival and departure by plane, train or car, shuttle, hotel with room type.
Dietary needs, comments, file upload and anything only your event asks.
Plus-one. With a record of their own.
Guests register their plus-one in the same form. The plus-one gets a separate record with a ticket, name badge and seat, and stays linked to the main guest. You decide how many plus-ones each guest group may bring.
- Fields per plus-oneName and whatever else you need from companions, such as dietary needs or the evening program.
- Capacity counts alongTwo people take two seats; once the limit is reached, they go on the waitlist.
- Linked to the main guestThe guest list shows who belongs to whom; check-in and seating use that link.

Full means waitlist. Not overbooking.
Capacity limits apply per event, per guest group and per workshop session. The form only offers what is still available; once a session is full, the guest joins the waitlist and moves up as soon as someone cancels. Registration deadlines close the form on the cutoff date.
| Capacity | Seats | Waitlist |
|---|---|---|
| Whole event | 500 | 7 |
| Workshop A · Session 1 | 40 | 12 |
| Workshop B · Session 1 | 40 | 0 |
| Park Hotel · Single | 60 | 3 |
| Press | 25 | 0 |
Event, guest group, workshop session, hotel rooms, side events: each with its own number.
Guests know they are waiting; once they move up, they get the confirmation and ticket automatically.
A registration deadline per capacity; after that, the form shows the waitlist or closes.
Dear Ms. Bergmann,
Thank you for registering. We look forward to welcoming you and your guest on October 24, 2026, in Hall 4.
Submit. Confirmed. Ticket in the inbox.
The confirmation goes out the moment the registration comes in: with the guest's details, ticket, calendar file and a personal link. With that link, guests update their own details, add a plus-one or cancel. Everything lands in their record.
- In your event's designConfirmation, reminder and cancellation as templates in event invitation emails.
- Attachments built inPDF and wallet ticket, calendar file, your own attachments such as the agenda or directions.
- Changes loggedWhatever guests change through their link is recorded in the change log, with a timestamp.
- Targeted remindersWho has not responded by the deadline is a filter in the guest list, not a mass email.
Online event registration: open, invite-only, or both.
A customer event invites people personally, a conference takes public sign-ups, and a summit does both: invite-only flows for VIPs and press, an open one for attendees. Each flow has its own form, capacity, languages and price.
Form, fields, capacity, price and confirmation per group; all in one guest list.
The form lives on your event website, on your own domain and in your design.
Registrations from your CRM or ticket shop come into the same list through the API.
The registration list keeps itself up to date.
Every registration is a guest in the guest list, with each field as a column. Who has confirmed, who is waiting, who picked which session, who is vegetarian: filters instead of spreadsheets. The dashboard shows where you stand, and exports go to the hotel, caterer and shuttle service.
- Fields as columnsWorkshop choice, travel, hotel and dietary needs: filter, sort and export.
- Lists for vendorsRooming list, catering numbers and shuttle plan as exports from the same registration.
- Real-time statusRecent registrations, waitlist and cancellations on the dashboard, no counting by hand.

A registration form collects personal data. That is why every field follows a rule.
Required fields only where necessary; consent for marketing and event communication collected separately and recorded per guest; hosting in Germany; access through roles and permissions. What guests enter is visible only to the people who need it.
- Hosted in GermanyRegistration and guest data on servers in Germany, under EU data protection law.
- GDPR compliantConsent per guest, data processing agreement and deletion policy in the Trust Center.
- TISAX assessedTISAX is the information security assessment standard of the automotive industry; AirLST has been assessed under it.
Every consent is stored on the guest record with a timestamp and can be filtered in the guest list: Event Marketing
Registration is the moment guests fill in their own record.
The invitation brings them in, the form captures their details, and from then on tickets, seating, check-in and reporting all work with exactly that data. No retyping, no reconciling.

What is event registration software?
Event registration software is a web-based tool for collecting RSVPs: guests confirm their attendance in an online form and provide what the organizer needs for planning, such as contact details, plus-ones, workshop choices, travel, hotel and dietary needs. The software builds the form without coding, checks capacity limits and deadlines, sends the confirmation and turns the submissions into the event's registration list.
In AirLST, registration is a function of the guest list: every registration is a guest record, every field a column. Invite-only registration runs through the personal invitation link, open registration through the event website; ticket types, payment and add-ons are part of the same form, and guests update their details later through their personal link.
The form is not a file someone has to retype. It is the guest filling in their own record.
How does online event registration work in AirLST?
- Build the form. Fields from the toolkit, required fields, conditions, help texts and languages; a separate flow per guest group if needed.
- Set capacity and deadlines. Seats per event, group, workshop session, hotel room and side event; a registration deadline and what happens at full capacity.
- Choose access. Invite-only through the invitation link or open on the event website, with or without ticket types and payment.
- Open registration. Guests fill in the form, choose sessions and program items, register a plus-one and pay if required; the registration becomes their record.
- Confirm. An email with their details, ticket, calendar file and personal link goes out right away; reminders and updates use the same template.
- Work with the data. Filter the registration list, export for the hotel, catering and shuttle, confirm guests from the waitlist, run check-in on the same data.
How is event registration software different from form tools and email replies?
RSVPs by email create work: someone reads, enters, follows up and counts. A general form tool collects answers in a structured way, but it delivers a spreadsheet that still has to be matched against the invite list, capacity, tickets and check-in; it does not know plus-ones, waitlists or personal links for changes.
Event registration software is a form that knows the guest list.
That is why capacity updates on submit, why a plus-one is a guest in their own right, why the ticket arrives with the confirmation, and why the workshop choice shows up on the scanner at check-in. And that is why there is no second list: the registration is the registration list. For registrations that start in other systems, such as your CRM or a ticket shop, the API brings the data into the same guest list.
What does registration connect to?
To event invitation emails, which send the personal link and design the confirmation; the event website builder, where the form lives; the guest list, which keeps every answer as a column; event ticketing for ticket types and payment; and to seating charts, event check-in and event reporting.
