Well, let's see now...
I jumped on board a Jetstar flight the other day with my wife and sat down in a couple of seats... and flew to MEL!
A week later my wife and I jumped on a return flight, grabbed a couple of seats... and flew back home!
So, tell me, why is this a problem?
Am I missing something here?
Did the same thing with Alitalia about 30 yrs ago...what's the problem guys??
