飞往费城，提前预订避开夏季高峰期的旅客会受益匪浅。美国航空在费城国际机场 (PHL) 占据主导地位，这使得竞争程度低于一些东海岸的竞争对手，但如果您仔细寻找，也能找到廉价航空和跨大西洋航班。最佳出行时间是淡季：春季和秋季票价显著下降，城市也最为宜居，而且您无需在七月四日独立日当天与熙熙攘攘的人群争抢一份费城牛肉芝士三明治。

Terminal A-West handles the transatlantic arrivals, and B/C gets clogged during American's morning push, so a spare half hour at security is money well spent. February fares dip to $89, which happens to match the New York run at 1h 10m, so the maths rewards patience over spontaneity. Independence Hall and the Liberty Bell don't care what the cost-of-living index says, and at $118 a day midrange, neither should you. Skip July Fourth and Thanksgiving unless a 50-70% fare hike sounds like fun.
