Singapore Airlines will reinstate its full flight schedule to and from London Heathrow by 2 June.
By then flight frequencies will be at pre-pandemic levels, SIA said.
The four daily flights will be operated by Boeing 777, Airbus 380 and A350aircraft.
To boost connectivity for regional customers, SIA and Loganair launched an interlining agreement on several routes.
Loganair flights from Aberdeen, Inverness, Teesside and the Isle of Man will connect to Singapore Airlines flights from Heathrow and Manchester.
“Singapore Airlines is delighted to announce this new interline partnership giving our passengers greater connectivity,” Mohamed Rafi Mar, general manager Singapore Airlines UK & Ireland, said.
