Methodology: learn how we calculate these charts

The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Philadelphia to Charleston cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.

Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.

Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.

The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.

Frequently Asked Questions

Everything you need to know about flying from Philadelphia to Charleston.

What is the typical flight duration from Philadelphia to Charleston?

Flights from Philadelphia to Charleston cover about 550 miles. The typical nonstop flight takes 1 hour and 56 minutes outbound, and the return leg takes 1 hour and 55 minutes—a difference of only one minute, so direction doesn't meaningfully affect the duration.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

Are there any direct flights from Philadelphia to Charleston?

American Airlines is the only carrier currently scheduled non-stop between Philadelphia and Charleston, with up to 19 weekly flights. Mainline American runs daily service, while American (operated by PSA Airlines) adds flights on Monday, Thursday, Friday, Saturday, and Sunday. Service runs every day of the week overall, with departures in the morning and late evening.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

What are the ground transportation options in Charleston?

Charleston International Airport offers a range of ground transportation options for reaching the city center. Ride-sharing services like Uber and Lyft are available at a covered shelter outside baggage claim, with a typical ride to the College of Charleston taking about 24 minutes and costing around $33. Taxis operate from a central median with a $17 minimum fare, and CARTA bus Route 11 provides scheduled service to downtown, typically taking 50–55 minutes. Rental car desks are located at the end of the terminal, and many hotels also offer courtesy shuttles. Ride-sharing is generally the most used and fastest option for most travelers.

When is the cheapest time to fly from Philadelphia to Charleston?

Fares from Philadelphia to Charleston are lowest in late January, around $243. January is the cheapest month overall, averaging $247, followed by September ($251) and July ($256). December is the most expensive month at about $305, and fares peak in late December at about $321. The yearly average is $268. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.

How far in advance should I book tickets from Philadelphia to Charleston?

Book about 4 weeks before departure for the best fares from Philadelphia to Charleston, around $260. Booking in the final days before the flight costs about $352, $92 more. Booking six months ahead runs about $443. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.

Are overnight (red‑eye) flights available from Philadelphia to Charleston?

There are no nonstop red-eye flights from Philadelphia to Charleston. The only overnight option is a connecting itinerary on United routed through Washington Dulles (IAD), where the red-eye leg departs IAD at 22:20 and lands in Charleston just after midnight at 00:15, with a roughly 1h31m layover.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Which airlines usually operate this route from Philadelphia to Charleston?

American Airlines is currently the only airline scheduled non-stop from Philadelphia to Charleston, operating under both its mainline brand and American Eagle via PSA Airlines. Mainline American flights run daily with about 10 weekly departures, while the PSA-operated American Eagle service adds roughly 9 more weekly flights on Mondays, Thursdays, Fridays, Saturdays, and Sundays. Combined, that's up to 19 weekly non-stop flights between the two cities. No per-carrier fares were provided for this route.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

How reliable are on‑time arrivals on this route from Philadelphia to Charleston?

Frontier Airlines is the most reliable carrier on the route from Philadelphia to Charleston, with 83.8% of flights arriving within 15 minutes of schedule and a 3.6% cancellation rate. Piedmont Airlines (operating as American Eagle) follows at 78.3% on-time arrivals with 2.1% cancellations, then Republic Airways (also American Eagle) at 77.8% with no cancellations, and American Airlines mainline at 75.6% with 1.6% cancellations.
Methodology
On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Which airport should I use in Charleston?

Charleston International Airport is the only commercial airport serving Charleston. It is about 12 miles northwest of downtown and is served by major US carriers including American, Delta, United, Southwest and JetBlue.

How do I get to Philadelphia Intl Airport from the city center?

From downtown Philadelphia, the fastest and most popular way to reach Philadelphia International Airport is the SEPTA Airport Regional Rail Line, which runs every 30 minutes from Center City stations like Suburban and Jefferson directly to the terminals. Ride-share services pick up at Zone 7 and metered taxis at Zone 5, offering door-to-door convenience at a higher cost than the train. Several SEPTA bus routes (37, 108, 115) also serve the airport for budget travelers, while driving and on-site or off-site parking remain options for those with their own vehicle.

Are there hotels or sleeping facilities at Charleston airport?

Several hotels are located near Charleston International Airport, including the Fairfield Inn & Suites Charleston Airport/Convention Center, which offers a complimentary shuttle to and from the airport, and the Residence Inn by Marriott Charleston Airport, which also provides an airport shuttle and sits about 1.4 miles away. The Homewood Suites by Hilton Charleston Airport/Convention Center is roughly one mile from the airport, and the Home2 Suites by Hilton Charleston Airport/Convention Center is minutes away. There is no on-site hotel within the terminal itself, so travelers arriving on a late flight will need to take a short shuttle or drive to one of these nearby properties.

What aircraft are typically used on flights from Philadelphia to Charleston?

American Airlines operates the most flights from Philadelphia to Charleston, with its Airbus A319 on daily service. American Eagle, operated by PSA Airlines, also flies the route using Bombardier CRJ-900 aircraft. Both carriers currently offer nonstop service on this route.
Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.

Which airline alliances serve flights from Philadelphia to Charleston?

On the nonstop route from Philadelphia to Charleston, American Airlines is the only carrier currently scheduled, flying up to 19 weekly flights (including regional service operated by PSA Airlines under the American Eagle brand). American belongs to the oneworld alliance, so oneworld is the sole alliance represented nonstop here. Other alliances may serve the route only via a connection.
