Bahraini national carrier Gulf Air has now resumed flights to Dubai and Abu Dhabi.
It means the airline is now flying to London, Paris, Frankfurt, Manila, Athens, Cairo and a number of destinations in Pakistan.
Emirates flights between the two countries already resumed in June and take place seven times a week, and flights with Etihad are also up and running once more between the UAE capital and Manama.
Anyone that arrives at Manama airport will have to take a COVID-19 test costing BHD30 (around Dhs300) before being allowed into the country.
The country's ministry of health said passengers can pay the charges via the Be Aware app, before boarding a plane heading to the kingdom.
Bahrain News Agency also reported that people must quarantine for 10 days upon arrival.
