And we know that how?
Some truth to this,
If you Google spirit airlines ban, it brings a somewhat similar story where after a passenger was asked to fix mask and they listened, but they still got a letter banning them.
It didn't seem like they were part of this who that are being targeted now.
However, these letters without anything at all is definitely next level.
I would think this issue is a combination of the type of flight attendants that they have, together with the reporting system that they have, which seems quite easy to be abused.
