Case Study: Fly Gangwon achieves rapid PSS migration and operational agility with IBS Software's iFly RES

Opening new skies for Fly Gangwon with an agile PSS migration

Fly Gangwon, a South Korean carrier that began operations in 2019, faced an urgent challenge when SITA announced the discontinuation of its PSS business. With strict de‑migration deadlines, pandemic pressure, complex integration needs across scheduling, distribution and Korea’s One Pass, and the need to preserve cash and revenue, Fly Gangwon selected IBS Software’s iFly RES (integrated RES and DCS) for its proven local track record and support for GDS, interline, direct channels and NDC APIs.

IBS Software implemented iFly RES in a five‑month, lift‑and‑shift migration hosted on AWS, working as a single team with Fly Gangwon to migrate data, integrate interfaces and train staff; the airline went live one month ahead of schedule. The solution preserved satellite systems, enabled rapid activation of sales channels, offered pay‑as‑you‑go SaaS elasticity (handling up to 100x promotional transaction spikes), and automated workflows so agents now process multi‑segment cancellations about 5x faster.
