ALLWIN AIR · Ancillary Gateway · Seoul, Korea

Sell ancillaries from multiple Korean airlines
through one integration

ALLWIN AIR is a B2B Ancillary Gateway System (AGS) that brings airline ancillary services to travel agencies, OTAs and partner platforms. Agencies earn new revenue without building airline-by-airline integrations, airlines extend ancillary sales beyond their own websites, and travelers buy flights and extras in one place.

What does ALLWIN AIR do?

ALLWIN AIR (올윈에어) is a South Korean B2B company that enables airline paid ancillary services to be sold through travel agencies, OTAs and partner platforms.

B2B only

We do not sell directly to consumers. We integrate ancillary services into our partners' booking flows (B2B2C) so that their customers can purchase them.

Multi-airline, single integration

Ancillaries from seven Korean airlines through one connection. We build and maintain each airline interface and absorb airline-side changes.

AI seat recommendation

Instead of a complex seat map, travelers get recommended seats based on the passenger and companion context, making seat selection simple and fast.
