Gulf Air is going to resume its services to Abu Dhabi and Dubai in the UAE from July 5.
The resumption of the flights means passengers can fly from London via its hub at Bahrain International Airport.
The national flag carrier of Bahrain discontinued some of its flights from London throughout the pandemic but is now bringing back 25% of its original network.
Three flights a week will operate among Bahrain and Dubai and Abu Dhabi.
Flights from Heathrow to Bahrain will currently operate three times a week, on Mondays, Thursdays and Saturdays.
Gulf Air used to operate 14 flights per week from London to Bahrain before March.
