It replaces the old behavior of manually comparing prices across airline and hotel sites, and of being forced into expensive rebooking after a missed flight. People keep paying through bookings, which shows the demand for cheap comparison and booking is real and recurring.
Users search and compare for free, then book through partner airlines and hotels; SkyAlliance takes an affiliate commission on those bookings. The exact commission rate or payout terms are not disclosed.
Travelers manually checking airline and hotel sites one by one, and being forced into costly rebooking after missing a flight.

The first users came from the founder's own circle: he shared the platform with airport colleagues to validate it, and the first booking was a Las Vegas hotel booked by his friend Zach Jenkins.

This is not an AI business, but its cold-start playbook transfers: collect real user behavior with tracking first, then run retargeting on a tiny budget instead of spending big upfront.

Revenue basis · Founder self-reported, unaudited (see source page)
Revenue is a self-reported ~£2,300/month, unaudited, and it is unclear whether this is gross revenue or net commission.
No affiliate commission rate, conversion rate, or booking volume is given, so the sustainability of the revenue structure cannot be judged.
The business shut down in 2024, but the source does not explain why, so it is unclear whether the issue was demand or operations.
