Will freely admit I havn't read every single post in this thread but here is my experience:
- Hardly ever been checked for carry on weight or dimensions when flying with Emirates (Qatar on the other hand where to the gram!)
- I have the July Carry On Pro and flew Sydney-Vienna without being questioned at all.
- The only issue I had was that some of the overhead bins (I was at the front in Premium Economy) were really tight for fitting.. The single bin right at the front I had to slam shut and felt like I was going to break something in my bag, but it made it without issue.
- July have been amazing to deal with whenever I have contacted them..
