Well the reason PETA wants the airline employee disciplined is because he or she allegedly told the two to throw the turtle away. The 22 year old sister is equally, if not more so, at fault. You are right though, they should have checked with the airlines if they could take the turtle on the flight. Most the articles covering this story neglect to mention that they were offered a later flight free of charge.It's really obnoxious to me that PETA is trying to have employees at the airline disciplined. These people never looked into whether they could bring a turtle on a plane... and just decided to do so, and then... even though they were offered the opportunity take a later flight at no extra charge, and to do something responsible with the turtle, instead, they threw it in the trash and got on the flight. Now, you want to tell me that the airline employees are somehow responsible for the stupidity of these people. Come on!
If PETA wants to make a statement about this, it should be that if you are going to own pets, you need to do so responsibly.
