777Brit, Sounds like there possibly may have been an, er, interface breakdown between Sabre and the GDS that EF uses for its data stream, as well.
We'll see how it all settles out. In the meantime, it has taken considerably less time to find award seats, availability for specific fares I am searching for, etc. using EF, so I'm not unhappy with what I do get. (I have found award seats between US and Australia on QF and on to Mexico on MEX, and have found scarce I class seats for ourselves - savings of thousands of dollars, and / or considerable time searching with alternative systems.)
