UK visitor visa, changing flight dates during application?

[drwyness]

Two questions here, the first is simple, is the 3 week processing time stated on the gov website realistic? We only have 3 weeks and 2 days between the flight and the appointment in the VAC but as detailed below this needs to be changed to over 4 weeks. Is it likely to be processed in time?

Second question, so the visa is actually for my girlfriend traveling from South Africa to visit me in the UK. She included her flight dates on the application as the 7th of June. However I work away and have been extended by 1 week and will be home later. Therefore we are looking to changing her flights to the 13th of June instead. Is this going to cause any problem with the visa application? I read that flight tickets are not even necessary but as she has already submitted them I am concerned that changing the dates now will raise a red flag if they check her booking and the original no longer exists. Also don't wan to leave changing the flight too late as its already pretty close. Any advice much appreciated.

Lets know where yours falls when granted. We only have 3 weeks and 2 days between the flight and the appointment in the VAC but as detailed below this needs to be changed to over 4 weeks.

If not all, most embassies and high commissions will tell you not to make travel plans till you get your visa so what you said is correct.
Since you have done so it is within your powers to change it however if you now change it (what is not necessary but which you have produced as evidence to support application) and CW checks flight booking status (which not sure CW will do) and it influences outcome of application .....
