Flights in and out of Qatar have become more difficult. Airlines like Etihad, Emirates, and Gulf Air stopped flying to Doha. And the severing of relations has created limits on Qatari-registered aircraft flying through the airspace of some of the countries involved.
Qatar does not have its own flight information region, it’s within the Bahrain region. The Doha terminal control area is from ground to 24,500 feet, and above 24,500 feet is the Bahrain Upper Information Region. Traffic is re-routing primarily via Iran. There are only two routes for air traffic in and out of Qatar.
