There are currently QR aircraft in Saudi and UAE airspace. If airspace is getting blocked, it hasn't happened yet.
Flights to Europe and US should be mostly unaffected (flying through Iran and Turkey airspace), but for Africa and South America the routing will be interesting, I guess Oman and then south of Yemen.
Well HUACA and I found a very helpful person. She looked at options. Have now rebooked the DXB-DOH-ARN leg to be direct DXB - ARN on EK in Y and on next day as it departs too early for our ex Aus arrival on same day. No J availability for dates we needed to fly on. Only 1 flight a day.I'm looking at alternatives to getting to Stockholm. We need to be there on a particular date just a couple of days later.
Thankyou so much for alerting me to this issue which gave me the chance to sort things out before the avalance of travellers.
