Per day could still be nowhere near 5%. Remember that, by definition, each person in that 87% total only flies on one day per year (or two days if RT). Whereas, by definition, the more frequent fliers fly on multiple days.
What this means is that on the average day, you could in theory have the majority or at least a significant minority of
seats flown by frequent fliers, despite them representing only a small proportion of the total
annual unique customers.
Without further information we can't tell the average seat mix just from the uniqueness stat.
