OK not exactly free... but I've noticed how expensive Thai flights are getting from Bangkok
Thai Website On line BKK-London 17/30 September rtn = 53 000 baht
But wait a minute.....
Buy the ticket in PP same dates = 1300 usd .......... 40 000 baht
SAME FLIGHTS, SAME DATES That's for economy.
In first, its clsoe to 190 000 ex BKK but circa 165 000 ex PP - on a one year ticket. Plus you get PP - BKK return in biz as a bonus.
