I'am surprised! Here in the east it's mostly the weather. LGA,BOS,EWR.have a lot of bad weather as does ORD and SEA.usually on the west side it's fairly nice.But who knows with all the flights these days? I go to BOS and DCA a lot and I'am used to weather delays if you can get used to them? I just go and hope for the best?
