Eastar Jet
A South Korean low-cost airline operating domestic and regional Asian services with a Boeing 737 fleet, primarily from Seoul and Jeju.
About Eastar Jet
Eastar Jet is a South Korean low-cost carrier founded in 2007. It began commercial operations in 2009 and uses the IATA code ZE and ICAO code ESR. The airline has experienced significant financial and operational disruption, including a prolonged suspension, restructuring and a change of ownership, before resuming scheduled flights in 2023. Its current identity remains focused on affordable, point-to-point travel within South Korea and to nearby international markets.
Seoul is Eastar Jet's busiest departure hub, followed by Jeju, while Cheongju and Gunsan also support its domestic presence. Its network covers 10 destinations across 5 countries through 18 routes. International flying is concentrated on short- and medium-haul Asian markets, with services linking South Korea to cities including Bangkok, Kota-Kinabalu, Osaka, Sapporo, Taipei and Tokyo.
Eastar Jet operates aircraft from the Boeing 737 family, with Boeing 737, 737-600 and 737-800 types represented in its operating record. The airline generally follows a single-class, economy-focused low-cost model. Seating, checked baggage, meals and other optional services can vary by fare or require an additional payment, so passengers should review the inclusions attached to their specific ticket before departure.
Eastar Jet is not a member of Star Alliance, SkyTeam or Oneworld, and passengers should not expect the reciprocal lounge access, through-checking or mileage benefits associated with a global alliance. The airline does not have a widely established frequent-flyer programme comparable with those of South Korea's larger network carriers. Travellers connecting to another airline should therefore treat separate bookings cautiously and allow ample time between flights.
The airline's compact network can be useful for direct leisure trips between South Korea and selected regional destinations, particularly when its schedules and fares suit the journey. Its low-cost structure, however, means the initial ticket price may exclude services that full-service airlines bundle into the fare. The relatively small network also offers fewer same-day alternatives during disruption, making travel insurance and flexible onward arrangements worth considering.

Flying with Eastar Jet — what to expect
Check Fare Inclusions
Eastar Jet's lowest fares may not include checked baggage, advance seat selection or onboard refreshments. Compare the total price after adding the services you need.
Baggage Rules Vary
Cabin and checked-baggage allowances can depend on the route and fare conditions. Confirm the current weight, size and item limits on Eastar Jet's website before packing.
Mostly Economy Seating
The Boeing 737 fleet is configured around low-cost economy travel. Travellers wanting a particular seat or additional convenience should review the paid selection options available for their flight.
Allow Connection Time
Eastar Jet is not part of a global airline alliance, so separate-ticket connections may not be protected during delays. Collecting and rechecking baggage may also be necessary.
Limited Recovery Options
A compact route network can leave fewer alternative flights when disruption occurs. Keep some flexibility in time-sensitive itineraries and monitor flight notifications before travelling.
