Discover Airlines (4Y, Frankfurt International) will retrofit the cabins of its long-haul A330-300s by mid-2028, unveiling an "ocean blue" interior, costing a "three-digit million euro sum", in what it calls the biggest investment in its five-year history. All sixteen A330s will begin receiving the new cabins from April 2027. After the refit, each aircraft will feature 288 seats: 227 in economy, 31 in premium economy, and 30 in business. There will be two front-row business class suites, a redesigned "hard-shell" premium economy seat, upgraded economy seating, touchscreens with Bluetooth, and free high-speed Starlink internet in all classes.
