Jenna,
Chett uses a technique that is more like Supporn than Brassard. Scrotal tissue is used to form the vagina while penile tissue is used to form the labia. I guess this is more complex than the penile inversion technique and also certainly explains why the surgery lasts about 6 hours versus 2.5 hours for Brassard. It probably also explains why recovery takes longer. Anyway, as I now have the time, a few weeks more or less is not going to make much of a difference.
As a follow up to my own original post, a bit of information for other future long distance travellers. Having spent a few hours looking around the web since yesterday, I got a business class return with Air France/KLM from Strasbourg to Bangkok (through Amsterdam on the way out and through Paris on the way back) for just over 2000€ ie. just a little over double the price in economy but with a much, much higher level of comfort, notably the 180° reclinable seats.
For a long flight after surgery which makes sitting a very uncomfortable experience plus risk of DVT, I think the extra 1000€ is a very good investment. For GRS Chett is also 5000€ less expensive than Brassard (8000€ versus about 13000€), so not only does this difference allow me to pay for the upgrade, it also pays for BA surgery.
Now I just have to keep focused on work for the three and a half months that remain before heading off, with serious bouts of butterflies already every time I think about it..
