Qatar Airways joins Emirates, Turkish Airlines and Etihad Airways who have also announced this week a lifting of the US ban on their flights.
In March, the United States imposed the ban on direct flights originating at 10 airports in eight countries -- Egypt, Morocco, Jordan, the United Arab Emirates, Saudi Arabia, Kuwait, Qatar and Turkey -- to address fears that bombs could be concealed in electronic devices taken aboard aircraft.
Qatar Airways said in a statement early on Thursday the ban had been lifted after the airline and its hub airport Hamad International met with all new US security requirements.
US transport officials were due to visit Qatar Airways, Emirates and Turkish Airlines on Wednesday to check that the latest measures are in place, a spokesman for the US Transportation Security Administration (TSA) told Reuters on Wednesday.
