Welcome to FlyerTalk. Within the last week, I was researching exactly the same thing and came to the same conclusion: There are no K fares in the IAH-LGW market until May 2004. I verified this in Sabre, so I'm not just relying on what the CO rep told me. I don't think that calling back to get a different rep is going to solve this one.

That's not to say there will be no K fares until then, but just that there currently are no fares that allow for a trip prior to May 2004. There could be one added tomorrow.

Considering that CO announced about a month ago that K fares will require an extra fee in addition to miles to upgrade to BF starting January 1, the cynic in me says that perhaps they withdrew the K fare in order to implement the change quicker. If K fares valid prior to May 2004 remain missing until after Jan 1 then suddenly re-appear, I think we'll have our answer.

In the meantime, I booked my IAH-LON flight on AA and upgraded a $500 fare.
