Air India is cutting capacity on several European routes and suspending nonstop services to Copenhagen and Vienna as higher fuel costs and the continued closure of Pakistan airspace drive a winter network overhaul. The airline is reallocating capacity to strengthen connectivity to Australia and Japan. The Tata Group-owned carrier is reducing frequencies to Birmingham, London Gatwick and San Francisco, while several Boeing 787 aircraft remain unavailable as they undergo cabin refurbishment and exterior repainting.
