No, I have not, but my mate Dennis has. Here are a couple of videos on his channel.
First up Dennis and Jeb Brooks on Royal Jordanian, followed by them hamming it up at Petra. https://www.youtube.com/watch?v=Fa66b1M7i6Q
Second Dennis with his mum on a flight from Amman to Amsterdam with comments at the end on the assessment by Dennis. https://www.bing.com/videos/riverview/relatedvideo?q=royal%20jaordainian%20bunnick%20youtube&mid=D61FC833847CDC5F28C1D61FC833847CDC5F28C1&ajaxhist=0
Both have great channels with lots of good stuff on airlines. Jeb Brooks has Greenergrass.com and often does trips with his wife, Suzanne. Alert both tend to fly business class, though not always. Both give honest and fun reviews.
My wife and I are off to Paris tonight, Saturday for us, on China Eastern via Shanghai, business. Long-haul is only option for us. Dennis did a review of this airline in 2019, and so my children have decided that we should try it as an alternative to the Gulf carriers, south Asian airlines, and the Red Roo. They will join us in a week in Rome.
Hope the reviews are of help.
