I think it is a nice idea
henkybaby, and especially so for being a little 'cryptic' to slow the pace of bookings and make it a little harder for BA to instantly clamp-down on. Some of the fares you mentioned are bettered out of vikingsville and there are a few nice fares over Xmas if you are willing to go CW one way and F another for a tea party. (not very good at cryptography here

)
