How does one even time this to take full advantage of the six month validity? The Thai consulate in L.A. says it takes a minimum of 15 business days to process. If you book a flight for say, November 15th, would you apply on October 25th (fifteen business days)? That'd be a little nip and tuck. Giving yourself more wiggle room and applying October 2nd should work but then if it is approved in 15 days you end up losing two weeks of time.
