That's a really disappointing source. The headline is '200,000 people a day fly without REAL-ID', which starts out quite interesting.

It then goes on to explain that the TSA has reported 93% of traveler's complied with REAL ID, citing a TSA blog from a week prior which in fact states the same.

They then take this and couple it with a single day, which they state was the busiest travel day of the Memorial Day weekend, and extrapolate that 7% of the travelers that day must've failed to provide a REAL ID.

For the sake of conversation, this is a reasonable statement. Going back and using it to suggest 200k fly without it on a typical day is not reasonable, nor is your suggestion that a 6 months later it's still at 7% (or even typical travel volume hasn't changed.) There has to be better data available.

I was curious about this, so I looked up travel volume. YTD the daily average is 2,130,136 passengers. At 7%, this is 149,109.5 passengers or $2.449 B a year in fees. This ignores that you only pay the fee once very 10 days and assumes that all travelers pay the fee on every occurrence.
