Flying from Philadelphia International
Philadelphia International is American Airlines' largest East Coast hub after Charlotte.

American operates the bulk of the schedule; Frontier and Spirit run heavy ULCC operations on leisure routes. Transatlantic service to Europe is dense — daily flights to London, Frankfurt, Madrid, Doha and Dublin make PHL the cheapest gateway for many small-city US travellers heading to Europe.

Morning summer fog (May–August) routinely causes ground delays; book afternoon departures or mid-day arrivals during that window.
