Singapore Airlines (SIA) will increase flight frequencies and boost passenger capacity across its network in the 2025 Northern Summer operating season (30 March 2025 to 25 October 2025), supporting the higher demand for air travel to several popular destinations.

From 30 March 2025, SIA will have a daily service to London (Gatwick), up from the current five-times weekly services. Together with its four-times daily flights to London (Heathrow), this will give the airline five daily services to London. In early August, SIA unveiled its newly-refurbished SilverKris Lounge at Heathrow Airport after a six-month renovation and it now offers seating for up to 242 passengers as well as upgraded facilities.

Services to Rome will increase to five times a week between 26 June 2025 and 28 August 2025, up from the current four weekly flights.

SIA will delink its three-times weekly Singapore-Milan-Barcelona flights from 24 June 2025 to 7 September 2025, and operate more direct flights between Singapore and the two European cities. The Airline will mount five-times weekly direct flights to Barcelona during this period, up from the current two weekly flights. Milan will have a daily service, up from four-times weekly currently.

Australia, Southeast Asia and South Africa

Flights to Adelaide, Australia, will go up to 10 a week across the Northern Winter 2024 and Northern Summer 2025 seasons, up from the current seven-times weekly services.

Frequencies to Ho Chi Minh City, Vietnam, will rise to thrice daily, up from 19-times weekly. Services to Cambodia’s second largest city, Siem Reap which is the gateway to Angkor Wat, will go up to twice daily, up from a daily service.

A three-times weekly service will be mounted to Johannesburg in South Africa from 11 December 2024 to 10 January 2025, and from 2 April 2025 to 24 October 2025, bringing the total number of flights to the city to 10 times a week, up from the current daily services, during these periods.
Aircraft changes, suspension of Houston flights.

The Airbus A380 will return to Tokyo (Narita) between 30 March 2025 and 31 May 2025 on one of its two daily services, replacing the Boeing 787-10. The A380 will stop operating to Mumbai from 28 July 2025 to 31 August 2025, and Delhi from 23 June 2025 to 27 July 2025, and will be replaced by the Boeing 777-300ER.

In line with its capacity adjustments, SIA will suspend services to Houston via Manchester from 1 April 2025. This move will bring an end to the world’s longest one-stop scheduled passenger service, connecting Singapore and Houston via Manchester. The airline will instead rely on its Star Alliance partners to serve passengers traveling to and from Houston. However, SIA will maintain five-times weekly services between Singapore and Manchester.

In June 2024, SIA announced that it will launch daily flights between Singapore and Beijing’s Daxing International airport located in the south of Beijing, on 11 November 2024. SIA will also increase its frequencies to Beijing’s Capital International airport to 21 weekly services from 5 August 2024, up from 18 weekly services currently offered. This means SIA will operate 28 weekly services to Beijing from November 2024.
