I only have small anecdotal evidence that when it FAILS to clear with that kind of a situation (i.e., F seats available), it is always a non-HoKeY fare.
It is not supposed to matter but clearly CO is doing something different from NW.
Theories:
1. Revenue management plays with the buckets and pulls and puts F seats so as to affect EUA. Of course, holding F seats until last minute is one thing, but taking it back to just miss EUA is quite a different thing.
2. The EUA algorithm has been changed to consider fare basis although this is not a published policy.
3. The EUA upgrades for certain fares (or all fares) come from a different bucket (than F) which is not visible on ITN.
4. EUA has software bugs. This is the least unlikely given NW uses the same software with no such reports.
