Planning a family visit in October from Austin, Tx to eastern Pennsylvania. Looking at SWA's low fare calendar nonstop flights and looking at 3 airports. We find that Newark is almost 50% cheaper at most times of the year. We always rent a car so we can make side trips when visiting, so driving distances for these three airports are not a factor for us. We prefer NS flights. We often fly into BWI since we like to stop in Gettysburg for a few days before heading on to see family but BWI has gotten a lot more expensive. Philly is closer to our family but there are NO nonstop flights, fewer flight options, and also more expensive. So we are considering Newark this time. It's been 12 plus years since we flew into Newark - I have read that security at this airport is lacking (many TSA failures in detecting contraband) and wondering if that is a factor? Any information or ideas from those who fly out of EWR why Newark is so cheap from Austin compared to the other two? AUS - EWR Newark $97 ($388 roundtrip for 2) - NS AUS - PHL Philly $180 ($675 roundtrip for 2 - (plane change) AUS - BWI Baltimore $180 ($715 roundtrip for 2 - (NS and plane change) Thanks all.
