Convergence

Convergence is the booking system used by IBA-affiliated tunnels in the USA. It’s the most tightly-integrated of the IBA’s external booking partners — going beyond simple member validation to cover member-specific pricing and booking-driven logbook entries.

What the integration does

Convergence and the IBA share enough state to make this a “two-way” integration rather than a one-way validation flow:

1. Member validation at check-in. Same as every integrated system — the tunnel sends the IBA a member ID and PIN; the IBA confirms identity and reports current standing.
2. Custom booking links. Each member can be given a personalised booking link that takes them to a Convergence affiliate store pre-loaded with their identity.
3. Member-tier pricing. When a member books through their custom link, Convergence applies pricing based on the member’s Convergence group — see “Groups and discounts” below.
4. Booking-driven logbook entries. When a flight booked through Convergence completes, the booking data flows back to the IBA so a logbook entry can be created (subject to the flyer’s currency).

Groups and discounts

The headline feature for members: Convergence sorts each member into a group based on their booking history. The more bookings a member has made, the better the pricing tier they qualify for.

In practical terms:

• A new member visiting their custom link sees baseline pricing.
• After enough bookings, they move up a group and see a different, better price the next time they book.
• Bookings continue to count over time, so loyal members keep moving through tiers.

The IBA doesn’t operate the affiliate store itself — Convergence does — but the IBA’s record of the member is what tells Convergence which group the member belongs to. So a member’s group reflects their full IBA flying history, not just bookings made through one tunnel.

Where to find a member’s custom link

The custom link is generated per member and lives in the member’s account on the IBA platform. Members can copy or share their own link; admins can look up a member’s link in the back-office tools.

What about the logbook?

Bookings that complete through Convergence trigger the same currency gating that applies to every booking-sourced logbook entry:

• Currency active → logbook entry created automatically.
• Currency lapsed → no entry; the member is emailed about recurrent training first.

This is the same rule the platform applies to any external booking flow. See Currency for the full picture.

Where this sits in the platform

Convergence is one of three external booking systems the IBA integrates with — alongside FuzeMetrix (non-USA tunnels, validation-focused) and Tunn3l (USA + global, coming soon).

Implementation lives in the API service under api/src/features/connector/convergence/. The interactive Convergence API reference (Phase 4) will be at /api/convergence-external and /api/convergence-internal.
