Odd availability listings - more R than C or D
I was looking at fare bucket availability for some upcoming flights and I noticed some odd patterns in CE where R is fully open at R9 but the some of the higher fare buckets are filling up. For example:
J9 C9 D3 R9
or
J9 C6 D2 R9
Is it usual to keep offering lots of discounted/restricted seats whilst reducing the number of semi-flex seats available? Or, is this about pushing those looking for semi-flex towards fully flex J?
