Apologies for the radio silence this end - I've been travelling London to NZ on Qantas via Dubai which is another saga which I won't go into right now ....

The good news is that YES - I did get my AONE4 ex Cairo reissued by BA with all the changes I wanted .. 2 hours before I was due to leave rural England and head to Heathrow to catch my next flight ......

That it took BA 8 days to manage this is simply beyond my comprehension ....... even more so given I had done all the work and checked that flights were all available in the correct booking classes and that the routing was valid.
My experience with the BA Ticket Agent over by the First Check in Area in Terminal 5 was very good and he clearly knew what he was doing and got all my flights sorted etc but of course the computer wouldn't come up with the sums etc and it needed to go to the rates desk to have the taxes recalcuated which I was told would take no more than an hour ......

The next 8 days were simply a saga of incompotence and laughable ignorance -as my previous posts might indicate .... I was told my routing was invalid because it didn't end in country of origin ...... when it clearly started and ended in Cairo
I was given a routing that took my London Paris Doha - then a surface segment at my own expense back to London and then a BA flight London to Cairo .....
And nobody could tell me why this was done ........

I spent hours and hours on the phone and on hold and was told repeatedly that I couldn't speak to anybody directly in the relevant department .....
Also I was told there was no supervisor I could speak to about the issues ...

To be honest I have no idea when on the 8th day - the day I was flying - BA having NOT called me back the previous day with the recalculation .... the agent I spoke to manage to get it done having put me on hold for barely minutes ...... and she had no insight as to why I'd had such an awful time of things other than to say - You're always better off getting an agent in Manchester with these things ........
I asked her where I had been calling and she said it looked like Newcastle
I pointed out that I was using the same BA Exec Club number each time ...

All my travel is done on RTW tickets as I'm based in NZ and this is the first time I've had one issued on BA ticket stock ...... and it is most assuredly the last.
I should with hindsight have called the AA RTW ticketing desk to see if they would take control of the ticket and pay them their 50 dollar service fee and be done with it and know that it would all be done in minutes
I will be looking into doing this should I need to make any other changes further down the line later in the year.

Maybe somebody on here flying on RTW tickets has experience with BA ticketing and can offer some advice as how to avoid this complete and utter and stressful and time-consuming fiasco ?

My advice is to get AA RTW ticket desk to take control of the ticket if you can ..... once you've flown the first segment of course,

Let me knowif you need any further info about Cairo Airport ---- leaving from the recently re-opened Terminal 2 was relatively painless and hassle-free !

Safe travels and Happy New Year to all
