On the same route, V can be cheaper than T? If both are available, would the web site offer you V or T? And would you ever see something like V0 S0 T9? I thought fare buckets were hierarchical, like you would never see Y5 B9 or B5 M6 for example, and if you had B5 M4 and purchased the M, then it would go to B4 M3. Are there certain pairs of buckets that are hierarchical, and others that are not?
And sorry, one more question if buckets aren't hierarchical. Suppose you have a V fare. Can you SDC onto a flight that has something like V0 W1?
