KLM Newsroom just got updated. As of tomorrow (22 January 2026), half of KLM's European short/mid-haul fleet will offer free Wi-Fi access to all Flying Blue members. It'll be available on A321neo, Embraer 195-E2 and a portion of 737-800 aircraft.
Assuming this means that all current Wi-Fi equipped aircraft will switch to a free model. Nothing has been said that would indicate KLM adopting Starlink like AF is doing.
Great addition for everyone, and a slight erosion of benefits for Ultimates.
