I just started a trial for EF, and I have a few questions:
1. Searching for Award flights. A result will show 3 legs of a flight. In the "available classes" if it shows nothing (blank) for a leg, does that mean that award availability is never given out on that flight? I am just looking for Business or First, and some legs show classes and seats available, so I assume if no class is shown, no awards are possible on that flight (ever?)

2. I am assuming there is no way to check CX or BA award availability? or is there a trick I can use to see it?

Thank you!
