Two mainline a day, a few CR7s and 2 Embraers. Yesterday (Monday) the Embraers were definitely cancelled due to weather.
Now all flights are sold out, and the last one has F only. So if the Embraer gets cancelled again (and I'm still not happy about flying it), then who knows if I'll even get back tonight (which really makes taking the 7:40am out of London sucky).
Just checked united.com & supposedly today the LHR flight is coming in 36 minutes late, so if that holds true, it would blow the early flight to ORD.
Cheers.
