Slipstream · How it works

One seat opens two.

A First Class founder is drawn by ballot. Their Friends & Family Pass seats two people in Business; those two each seat two in Premium Economy; and so on, until the line closes in Economy. Here is one founder’s line.

This is one founder’s line — 1 + 2 + 4 + 8 = 15 seats. Edition 01 runs 100 of these lines at once: 100 founders → 200 → 400 → 800 = 1,500 numbered seats. Your cabin is set by who seated you, not by how fast you buy.

The terms

Plain words.

Slipstream
How the edition spreads. Every owner can pull two more in behind them — the cabin below — like the draft a jet leaves for the one following. One founder’s whole chain of invitations is their line.
Cabin · class
Your tier: First, Business, Premium Economy, Economy. Set by who invited you, never by how fast you buy.
Boarding pass
Your own seat — your number and your cabin.
F&F Pass
Friends & Family Pass. The pass every owner gets to seat two people one cabin below them. Named after the benefit airline staff use to bring their people aboard.
Manifest
The live record of the edition: every numbered seat, who holds it, and which cabin. Enter your code on the Manifest to find your boarding pass and your line.
Founder
A First Class seat, drawn by ballot. Begins a line — and the one cabin no one can be invited into.
Closer
An Economy seat. The end of a line: no F&F Pass, so it brings no one else aboard. That’s what caps the edition at 1,500.
