Do you have any reason to believe that yesterday's flight was late because of weather? There is no guarantee that the inbound aircraft from LGW did the return trip. In fact, it looks like both inbound flights yesterday LGW-IAH arrived pretty much on time. Perhaps it was a delay due to something else (mechanical?)
CO35 for
today, which uses the plane from last night's outbound is 1.5 hours late. CO5 is 4 hours late.
But things don't seem to be that bad at LGW. On the other hand, when I browsed through some UK news website, the fog situation at LHR is almost - but not quite - as big a news as the snow in Denver.
Anyways, thanks for all the responses. I'll call the Elite desk and see if they can switch us now. If not, I'll definitely try the $25 confirmed standby.
The consequence of missing our Ryanair flight out of STN is too severe, even if we have travel insurance that covers this type of things.
Oh yeah, and we will bring our President's Club passes, so that we can get help from there if needed.
Thanks to all who've responded.
