Now, if your ME airline believes that flying "10000 miles" with no "Adequate En-route Airport" with "weather above landing minima" is acceptable, then rest assured I'll be avoiding that airline!
My ME airline, My Australian airline,my Japanese airline and BOTH my UK based airlines- Guess I just know how to pick 'em.
Kindly name the airlines who's FOMs you checked and quote the requirements for weather minima non-ETOPs from them. (happy to reciprocate afterwords). You've shown a marked inability to interpret manuals so far- I'd be surprised if it didn't extend to your claim that most airlines impose these restrictions over and above the regs.
