Well looks like the move is going ahead ...
I sent another E-mail to AirAsia, asking them if they could find out from the people who would know about a move to LGW, This time this is what I got back.
AirAsia Hello again Darren, unfortunately we have no information about a move to Gatwick. I have spoke to our route and development team and they have no infomation about any move from Stansted to Gatwick.
However my mate has found out that AirAsia
WILL MOVE to Gatwick, Not in September but on the 23rd October.
