thanks for the tip - and i apologize if this is in the faq somewhere. didn't know you could see that information directly on united.com.
so what is the significance of a flight which doesn't even list NC or NF vs ones which list NC0 or NF0? in about 10 different combinations i just looked at i didn't see a single one with a positive NC or NF number and most just don't list it at all...
