L/7 U/0 T/0 E/2??
Interesting extra data point from a flight I've got coming up.
If E really is simply a lower priced fare bucket, then I find this very strange.
I don't have expert flyer, but I feel like I've seen this type of fare availability when others post award/upgrade fares, not lower priced revenue fares.
Add me to the list that doesn't really feel like SMI's answer was conclusive. I'm cautiously waiting to see how this shakes out.
