We have flown Delta Express out of Newark. They are fine but they do cancel flights so you have to keep checking their web site, and make sure they have a phone number on file to call you if there is a last minute change. One time they called us at 3:30AM to tell us our flight for the morning was cancelled. They told us that if we drove to Newark, they would give us taxi money to go to Laguardia. The taxi ride at 8:30AM took almost 1 1/2 hours and we will not do that again. We are using them again in February.
