on the topic of united canceled flights, it seems to me from quite a few years experience, that the mel - lax / sfo route has a ratio of cancellations / delays. plenty of australians have been stuck in lax / sfo over shaboss when the wednesday flights gets cancelled.
yesterday both ua 99 and 61 were cancelled, ua 99 is delayed today by 2 and half hours..
i wonder if the numbers actually back this up [or united are like this all around the board]
