Aussierotor,
Great post and I couldn't have put it better myself.
Advertising cheap fares all the time gives the impression that they must be cheaper all together. Very wrong!! Virgin Blue seem to have so many different types of fares on the internet and finding a cheaper one than QF can be a challenge but at least with QF internet fares they are there right in front of you with out having to do too much searching.
JetStar is going to make the next few years very interesting around here. Just as it seems Virgin Blue were slowly getting away from the cheap fares, enter JetStar and the race is on again.
The only winners in this race will be the passengers, which is the way it should be.
