Korean Air has announced that upgrades to the in-flight Wi-Fi and roaming systems on its Airbus A350 aircraft will begin on July nineteen, twenty twenty-six. The work will be introduced gradually rather than across the entire fleet at once, with each aircraft receiving the updated technology in turn. As a result, onboard internet availability may vary depending on the aircraft assigned to a particular flight while the programme remains in progress.

The airline said that Wi-Fi and roaming services could be temporarily unavailable on certain A350 flights throughout the upgrade period. No completion date has been announced, and the programme will continue until further notice as additional aircraft receive the new onboard systems designed to enhance connectivity in the future.

How to Prepare for a Flight Without In-Flight Wi-Fi

Passengers planning to stay connected throughout a flight should prepare before arriving at the airport, especially when travelling on an Airbus A350 during the upgrade period. A few simple steps can help avoid unnecessary inconvenience:

  • download films, music, books and podcasts before departure;
  • save boarding passes, hotel reservations and transport details directly to a mobile device;
  • complete any work that depends on cloud storage or an internet connection before boarding;
  • send important messages in advance rather than expecting to be online during the flight.

Anyone expecting to communicate during the flight should consider notifying family members, friends or colleagues that responses may be delayed until after landing. Important booking confirmations, hotel reservations, transport details and other travel information are worth saving directly to a mobile device instead of relying on online access. Since the upgrades are being introduced aircraft by aircraft, the availability of Wi-Fi may differ even between flights operated by the same airline.

Only the onboard Wi-Fi and roaming services are expected to be affected, with no changes announced for any other part of the journey. Although losing internet access may require a little extra preparation, the upgrade is intended to improve onboard digital services over time. Planning ahead and keeping essential information available offline will help passengers avoid unnecessary inconvenience until the modernised systems have been introduced across the airline's Airbus A350 fleet.
