Yemen airspace has been Prohibited to Qatar Airways for over 2 years. Hectopascals has made 2 posts and both completely wrong.
But irrelevant anyway as we can't get through UAE or Saudi airspace to get there.
And there goes QR1427, enroute to Addis more or less half way between Riyadh and Mecca. Plus 4 more to the north. Stop it! It may be true tomorrow but it certainly doesn't seem that way today.
And as for the poster who claims Qatar's food is imported via Saudi Arabia; heve you ever actually been there? Doha is q good sized, busy port. Full of ships. While Mesaaieed port, to the south of Doha, has a dozen or so ships alongside. Same goes for the post re gas imports to the UK from Qatar. If the UAE wanted to bar these ships from their waters, it wouldn't matter to Qatar as they are currently pals with Iran so they would sail on their side of the Gulf.
