I had been having the same issue with blank pages and found that the Hush content blocker I have installed was causing it. I've reported it to Hush. If you're seeing this, go into Settings > Safari > Content Blockers and see if there are any enabled. If there are, try turning them off. If that helps, see if the content blocker app has a way to specify domains that should be allowed and add flyertalk.com to the list. Sadly, Hush doesn't offer manually "allow lists" like this.
