Yeah, exactly. They were the same price in EGP ex-CAI for many years before this. There was no error, they were issued at the correct EGP price that had been standing prior to the EGP devaluation. But even at that, they're not significantly cheaper than ex-OSL and ex-TYO that are currently available. I think I saved $2000 on my ex-CAI vs. an ex-TYO, that's hardly something to call an error fare. Pre-devaluation the ex-CAI price in $ was similar to ex-OSL, both are / were highly susceptible to swings from YQ charges (ex-TYO is not). In my case it just so happened to be that I had a chance to build in a stopover in DOH so I didn't have much in terms of positioning for the CAI departure, but for many others, that $2000 savings may have been eroded away by positioning.

Since then I've spent an additional $125 for a no-show because I slept through my alarm, then later I was willing to spend an additional $125 for a change that QF wouldn't issue because it was 2x stopovers in the same city, so had to buy a separate $200 for that for 3 hours on an LCC that certainly wasn't a highlight of my trip. (Thanks JL for zero availability to KUL which would have saved time and a tiny bit of money even with the change fee)
