Flying Out of Charleston: Airports, Airlines, and What to Expect

Charleston has two airports that handle commercial flights

Charleston International Airport (CHS) is the main hub for commercial travel in the Lowcountry. It sits about 12 miles northwest of downtown Charleston and handles the vast majority of passenger flights. Most major U.S. airlines operate here, including American, Delta, Southwest, United, and JetBlue, along with regional carriers and seasonal routes.

Coastal Carolina Regional Airport (CRW) in Myrtle Beach, about 100 miles north of Charleston, offers another option if you're willing to drive. It's smaller than CHS but sometimes has competitive fares or flight times that work better for your schedule. The drive takes roughly 90 minutes depending on traffic.

CHS is the practical choice for most Charleston-area travelers. The airport has been expanding its terminal and adding gates in recent years, so check the airport's website before you go to see which airlines are currently operating and where they're located in the terminal.

Key Takeaways

• Charleston International Airport (CHS) is 12 miles northwest of downtown and serves most major U.S. airlines with direct flights to dozens of destinations.
• Arrive at least two hours before domestic flights and three hours before international flights to allow time for parking, check-in, and security.
• Parking at CHS includes short-term lots near the terminal, economy lots with shuttle service, and off-site valet options; rates and availability change seasonally.
• Ground transportation from CHS includes rental cars, rideshare services, taxis, and airport shuttles; the choice depends on your destination and budget.
• Peak travel seasons in Charleston (spring and fall) mean busier airports and higher fares, so booking in advance and arriving early are especially important.

Getting to Charleston International Airport

If you're driving, CHS is accessible from I-26 heading northwest from downtown. Follow signs for the airport exit; the drive from downtown takes 20 to 30 minutes depending on traffic and time of day. Rush hour (roughly 7 to 9 a.m. and 4 to 6 p.m.) can add significant time, so plan accordingly if you're catching an early morning flight.

Rideshare services like Uber and Lyft operate at CHS. Fares vary based on demand and time of day, but expect to pay $15 to $30 for a ride from downtown Charleston. Taxis are available at the ground transportation level; you can call ahead or hail one at the taxi stand. Airport shuttles run from various hotels and parking facilities; ask your hotel if they offer shuttle service.

If you're parking at the airport, CHS offers several options. Short-term parking is closest to the terminal but costs more per hour. Economy parking is farther away but cheaper; shuttles run frequently between the lot and the terminal. Valet parking is available if you prefer not to navigate the lots yourself. Check current rates on the CHS website, as they fluctuate by season.

What to know before you arrive at security

The Transportation Security Administration (TSA) runs security screening at CHS. Arrive at least two hours before a domestic flight and three hours before an international flight. This gives you time to park, check luggage, and move through the security line without rushing. During peak travel periods (spring break, summer, Thanksgiving, Christmas), lines can be longer, so arriving even earlier is wise.

Have your ID and boarding pass ready when you reach the security checkpoint. Liquids, gels, and aerosols must be in containers of 3.4 ounces or smaller and placed in a single quart-sized clear bag. Electronics larger than a cell phone must come out of your bag. Shoes, belts, and light jackets can usually stay on, but follow the TSA officer's instructions at your checkpoint.

If you have TSA PreCheck or CLEAR, you can use expedited screening lanes at CHS. PreCheck costs money upfront but can save time on future trips. CLEAR uses biometric scanning to speed you through the identity verification step. Both programs have enrollment centers in the Charleston area if you want to sign up before your trip.

Airlines and destinations from Charleston

CHS serves destinations across the United States and a few international routes. American Airlines, Delta, Southwest, and United operate the most frequent flights, with service to major hubs like Atlanta, Charlotte, Dallas, and Washington D.C. From those hubs, you can connect to nearly anywhere. JetBlue offers direct flights to New York and Boston. Frontier and Spirit provide budget-friendly options to select destinations, though they charge for carry-ons and checked bags.

Direct flights from Charleston are available to roughly 30 destinations, depending on the season. Summer and fall typically see more routes as airlines add seasonal service. Winter and spring have fewer options but can offer lower fares. Check the CHS website or search directly with airlines to see current routes and schedules.

Booking directly with an airline or through a travel website like Google Flights, Kayak, or Expedia lets you compare prices and times. Fares from Charleston tend to be highest during peak tourist seasons (March through May and September through November) and around major holidays. Booking several weeks in advance usually yields better prices than waiting until the last minute.

Terminal layout and amenities

CHS has one main terminal building with two concourses. The terminal includes restaurants, cafes, shops, and charging stations. Restrooms are located throughout. If you have time before your flight, you can grab food or browse the gift shops. Free Wi-Fi is available in the terminal, though you may need to accept terms and conditions to connect.

The airport has a small art collection and local vendors that reflect Charleston's culture. You'll find Lowcountry-themed gifts, local snacks, and regional restaurants. Prices are higher than downtown, so eat before you arrive if you're budget-conscious. The terminal is generally clean and well-maintained, though it can get crowded during peak travel times.

If you're catching a connecting flight, allow at least 90 minutes between flights for domestic connections and two hours for international connections. CHS is not a major hub, so connections are usually straightforward, but delays happen. Check your airline's website or app for real-time gate and status information.

Traveling with checked baggage and special items

Each airline has its own baggage policies. Most allow one free checked bag for domestic flights, but budget carriers like Frontier and Spirit charge for checked bags. Carry-on bags are usually free, but size restrictions apply. Check your airline's website before you pack to avoid surprise fees at the counter.

If you're traveling with sports equipment, musical instruments, or other special items, contact your airline in advance. Some items require advance notice or special handling. Firearms and ammunition have strict rules and must be declared and packed according to TSA guidelines. Hazardous materials like certain batteries, lighters, and flammable items are prohibited or restricted.

Oversized or overweight bags incur extra fees. Weigh your luggage at home before you leave for the airport. If you're over the limit, you can repack at the airport, but this takes time and may delay you. Many travelers use luggage shipping services to avoid baggage fees and hassle, especially for longer trips.

Peak travel times and how to avoid them

Charleston's tourism peaks in spring (March through May) and fall (September through November). During these periods, flights fill up quickly, fares rise, and airport crowds increase. If you're flying during these seasons, book your tickets weeks in advance and arrive at the airport extra early.

Summer (June through August) is busy but slightly less crowded than spring and fall. Winter (December through February) is the slowest season except for the Christmas and New Year holidays, when the airport is packed. Weekday flights are generally less crowded than weekend flights. Early morning and late evening flights tend to have shorter security lines than midday flights.

If your travel dates are flexible, flying on a Tuesday, Wednesday, or Thursday instead of Friday through Monday can mean shorter lines and sometimes lower fares. Checking flight prices across multiple dates using Google Flights or Kayak can help you spot the cheapest days to fly.
