I was thinking JetStar must have had it in for the poor fellah, but then I remembered that they stuffed me up big time on 3 out of 4 trips with them, so now I wouldn't touch them with a 10ft barge pole.
In my view they are a total disgrace, which reflects badly on the good name of Qantas.
Tigerair used to be Australia's worst airline, but since being bought by Virgin, they have really turned things around, and for a discount airline I have found their service quite acceptable on numerous occasions.
