you don't have your status listed but I'd be interested to know I'd this was via the platinum or regular line?
red roo... the phone agent attitude outlined above is not exclusive to the booking of mASAs.
as a former platinum I found reservations staff extremely helpful and knowledgeable. they worked with you to achieve outcomes.
as I dropped down the status ladder and became exposed to the general call centre, the knowledge and assumptions by some phone agents have changed accordingly.
gone, in many cases, is the predisposition to work with you. gone, in many cases, is the predisposition that I, the passenger, might actually know what I'm talking about.
it's not uncommon now to get a response 'you can't do that', or 'you have never been able to do that'. when clearly we can/could. even a request by the passenger to 'please try' can be met with an indignant 'I've already told you that it's not possible [and I am the expert working for qantas so I should know]'.
I think it was a former Lufthansa CEO who went on the record as saying that his airline recognises even their top premium passengers will sometimes fly economy. and so the economy experience still has to be as respectful and pleasant as possible.
it might be a good idea for this mantra to be shared by supervisors at call centre team meetings. this might include some sort of recognition that contact with the call centre is part of the overall experience with qantas. that a 'we know better' attitude by call staff may not cancel the immediate sale, but it might detract the passenger from further bookings with qantas. that sometimes a passenger might actually have a valid point which should be explored rather than dismissed out-of-hand.
on landing, several American airlines include a line stating 'we know you have a choice of carriers and appreciate you choosing to fly with us today'. it would be mighty nice if those not pulling their weight in the qantas call centre believed that as well.
