"Regarding changes in air pattern, we really saw a spike happening in spring 2015," said Doug Yakel, a spokesperson with SFO.
It got so bad that Congresswomen Anna Eshoo of Palo Alto sent out a survey to local residents then reached out to the Federal Aviation Administration, or the FAA.
NextGen is being implemented at several airports. Using satellite technology, pilots can use the most efficient way to get from point A to B.

The SFO noise abatement office acknowledges getting complaints from several communities around the Bay Area.
If you try to call, their voice message says, "Due to an unusually large volume of noise complaints we're receiving, your response may take up to four weeks."
Meanwhile, the FAA says it's committed to study these concerns and make revisions to air patterns.
