F. Nose, the airline appears to have been well aware of its responsibilities and did not deprive anyone of their liberty to leave the aircraft.
Notwithstanding "common carrier" obligations, methinks danieldaniel's point would win the day in court. A trader surely has the right to decline business from those who seek to disrupt their activities - whether because they don't pay on time, or as in this case, because they incur costs which would be difficult to recover and also because they disrupt other legitimate customers who could then go elsewhere if they thought that the trader was not serving their best interests.
I would love to see these dopes actually challenge this in court to see how it plays out.
