First off, I grew up underneth a landing pattern for EWR. My parents bought the house without know it was there. It has not bothered them one bit in the 25 years they have lived there. Then again, They lived under the pattern for PNS (Pensacola) for a year and a half in the late 70's which they said was worse (they moved to NJ for job oppurtunities).
Secondly, if a two hour delay is the worst of their complaints, they need to find something occupy their time a little better. I've been stuck overnight at DFW when I've had to be back at my office the next morning. The people who have job commitments or important family obligations (weddings, sick family, etc...) might be the only ligitimate thing to complain about when you get stuck with a delay or cancellation but still won't accomplish anything.
Flight delays and cancellations are a part of air travel, especially during the winter. Going into things thinking it will not happen ever is foolish.
