Sad to see what's happened to UAL. Heathrow slots are the best thing out there (Just ask CO, who payed out the nose for them. Or United, who got theirs from Pan Am, signaling the death knell of the once great "Clipper"). United leasing them to a competitor seems asinine - why lease a route between the largest air travel market in the world and the gateway airport to the rest of the world (AA is even rumored to break even on it's RDU-LHR flight w/ just premium passengers and cargo, the economy is all gravy!) Then again, that seems to be SOP for UA these days, unfortunately.
