Cheap Flights from Seattle to Philadelphia — $96

Seattle is primarily served by Seattle–Tacoma International Airport (SEA), a large international hub popular with legacy carriers like Alaska Airlines and Delta and a range of international and domestic connections; Seattle also sees budget and regional flights through nearby smaller fields for charters or general aviation. SEA sits about 14 miles south of downtown Seattle, typically reachable by Link light rail in around 35–45 minutes for a modest fare, or by taxi/rideshare in 20–40 minutes depending on traffic with higher costs; shuttle and rental-car services are also common. The airport is usually efficient and well-equipped for long-haul travel, though peak-hour congestion and occasional weather delays can affect comfort and timing.

Philadelphia International Airport (PHL) is the region’s main international gateway and a full-service hub that typically serves major carriers and several international airlines alongside low-cost operators. Located about 8 miles southwest of downtown Philadelphia, it usually takes 20–30 minutes by car depending on traffic; public transit via SEPTA Regional Rail or Airport Line runs about 25–35 minutes with fares generally in the low-single-digit range, while taxis and ride-shares can be quicker but cost more. PHL offers broad amenities and frequent long-haul connections, making it convenient for business and international travel, though peak-hour traffic and security queues can add time; smaller suburban airports can be cheaper for domestic budget fares.
