Well thank you Wilco & Reductionist, I do appreciate your input, however, not your comments about my attitude and behaviour towards Qantas staff which is completely untrue and uninformed.
I have never once demanded any change - it has always been politely requested and that is my right as a regular customer with Qantas.
The truth is, all I actually want for my family is to get them to London earlier - it has nothing at all to do with demanding anything, and BTW I don't want Qantas to do anything other than to try and change our dates of travel.
My main issue (and therefore the subsequent complaint to Qantas) was that this first enquiry started around 10 weeks ago and I feel at that time they could have changed the seats as there were many available.
With regards to Wilco's comment;
It never hurts to ask, but from reading your post, it seems like you have asked several times over several weeks and im not sure how many times you need to be told "NO". Further to that, I read your posts as being exceptionally demanding and impolite despite your assertions to the contrary.
For your reference each time I called to speak to Qantas Platinum I was advised to call back in another weeks time to check if the situation has changed. Which I always did to ensure I could try and secure the earlier flights.
If the Qantas staff had the same attitude as you i.e. "how many more times do I have to be told no" then I wouldn't fly them at all.
In addition I really have no idea how you have found my posts to be "exceptionally demanding and impolite" despite my assertions to the contrary
I really quite surprised by your comments made and quite upset to read these.
