Air India has announced a number of additional frequencies on key routes as part of its Northern Summer schedule effective from March 30.

In a statement, Air India says that it has added three weekly flights from Delhi to Heathrow, increasing the number from 21 to 24 weekly flights operated by a combination of Air India’ flagship A350-900 and upgraded B787-9 aircraft. Additionally, it has also increased the frequency of its Amritsar to Birmingham and London Gatwick to four flights a week.

The statement also highlights addition of flights in the Delhi to Zurich, Delhi to Vienna, and Ahmedabad to London Gatwick routes. Additionally the airline has switched from A321 to B787 Dreamliner on its seven weekly flights from Delhi to Hong Kong.

Air India also says that the modernisation of its narrowbody aircraft is progressing well, and will be completed in mid-2025, while the first of the legacy widebodies, a Boeing 787, will commence retrofit of new seats and entertainment systems in April and re-enter service in October 2025.

Thereafter, two-to-three B787s will be inducted per month until all 27 legacy aircraft have been upgraded.

According to the statement, retrofit of the Boeing 777 fleet with new seats and entertainment systems, originally due to commence in 2025, will now commence in early 2026 due to production constraints at the selected seat supplier.

Arising from the retrofit programme and consequent temporary reduction in the operational fleet, the airline will suspend its non-stop Mumbai-Melbourne service between March 30 and September 13, and the non-stop Kochi-London Gatwick route from 30 March 2025 until further notice.

Air India will continue to operate 12 weekly flights to London Gatwick from Amritsar, Ahmedabad and Goa.
