Flying American Airlines From South Carolina Airports

What American Airlines offers from South Carolina

American Airlines operates flights from South Carolina's two largest commercial airports: Charleston International Airport (CHS) and Greenville-Spartanburg International Airport (GSP). From Charleston, American offers direct flights to major hubs including Dallas/Fort Worth, Charlotte, and Miami, with connections to hundreds of destinations worldwide. From Greenville, the airline provides service to Charlotte and other connecting cities.

American is one of the "Big Three" U.S. carriers and operates both mainline aircraft and regional jets through its American Eagle regional partners. The airline carries roughly 900 million passengers annually across its network, making it a common choice for travelers departing from the Lowcountry and Upstate.

The airline's frequent flyer program, AAdvantage, lets members earn miles on flights and through partner merchants. Miles can be redeemed for future flights, seat upgrades, or other rewards. Members also receive benefits like priority boarding and checked baggage allowances depending on their membership tier.

Booking and managing your reservation

You can book American Airlines flights through the airline's website (aa.com), its mobile app, or by calling 800-433-7300. The website and app let you search by date and destination, compare fare types, and add seats, baggage, or other services before purchase. Prices vary based on demand, time of booking, and how far in advance you reserve.

Once booked, you can manage your reservation online or through the app to change your flight (subject to availability and fare rules), add baggage, select seats, or add special services like wheelchair assistance or unaccompanied minor care. American allows online check-in starting 24 hours before departure, which you can do on the website, app, or at airport kiosks.

If you need to cancel or change your flight, the terms depend on your ticket type. Basic economy fares typically do not allow changes or refunds, while higher fare classes offer more flexibility. Checking your specific fare rules before booking helps you understand what changes cost and what options you have.

Baggage, seats, and add-on services

American's baggage policy varies by ticket type and frequent flyer status. Most passengers can bring one carry-on bag and one personal item (purse, laptop bag, backpack) at no charge. Checked baggage fees apply to basic economy tickets; AAdvantage members and passengers with higher fare classes often receive free checked bags. The airline charges for additional bags beyond the included allowance.

Seat selection is free for window and middle seats in most cabin areas, but premium seats (extra legroom, bulkhead, exit rows) carry an additional fee. You can select your seat during booking or later through your reservation. Basic economy passengers may have limited seat choices or pay to select a specific seat.

American also offers paid services including priority boarding, seat upgrades, lounge access for premium cabin passengers, and in-flight food and beverage purchases on longer flights. Frequent flyer members at higher tiers receive some of these benefits automatically.

The AAdvantage frequent flyer program

AAdvantage members earn miles on every American Airlines flight based on distance traveled and ticket type. You can also earn miles through partner credit cards, hotels, car rentals, and retail purchases. Miles accumulate in your account and can be redeemed for flights on American or its partner airlines, seat upgrades, or other rewards.

The program has several membership tiers: AAdvantage (free), AAdvantage Gold, Platinum, Platinum Pro, Diamond, and Diamond Elite. Higher tiers unlock benefits like priority boarding, free checked bags, seat upgrades, and lounge access. You move up tiers by flying a certain number of miles or segments in a calendar year, or by holding an AAdvantage credit card.

Award flights (those purchased with miles) can sometimes offer better value than paid tickets, especially on premium cabins or long-haul routes. However, award availability varies by route and date, and popular flights may have limited award seats. Booking further in advance typically increases your chances of finding available award flights.

Checking in and arriving at the airport

American recommends arriving at least two hours before domestic flights and three hours before international flights. You can check in online 24 hours before departure through the website or app, or at airport kiosks and ticket counters. Mobile boarding passes are available through the American Airlines app.

At Charleston and Greenville airports, American operates dedicated ticket counters and baggage claim areas. Both airports have TSA PreCheck and Clear enrollment centers, which can speed up security screening if you are a member. TSA PreCheck costs around $78 to $85 for five years and allows you to go through expedited security lanes; Clear costs more but lets you skip the security line entirely.

If you are traveling with checked baggage, drop it at the ticket counter or bag drop kiosk before heading to security. Baggage is typically loaded onto the aircraft about an hour before departure, so arriving with time to spare ensures your bags make it on your flight.

What to know about delays and cancellations

Flight delays and cancellations happen for reasons including weather, mechanical issues, crew scheduling, and air traffic control decisions. American's website and app show real-time flight status, and the airline sends notifications via email or text if your flight is delayed or canceled. You can also call 800-433-7300 for flight status information.

If American cancels your flight, the airline must rebook you on the next available flight at no additional charge, or offer a refund. If a delay is within American's control (mechanical issue, crew problem), you may be may have access to to compensation under Department of Transportation rules, though the airline does not always volunteer this information. If the delay is due to weather or other circumstances beyond the airline's control, compensation is not required.

Travel insurance purchased separately from the airline can cover costs if you miss a connection or need to rebook due to a delay. Some credit cards also offer travel delay reimbursement as a cardholder benefit.

Frequently Asked Questions

Can I bring a pet on an American Airlines flight?

American allows cats and dogs in the cabin on most flights for a fee (typically $125 each way). Pets must fit in a carrier that fits under the seat in front of you. Larger animals may need to travel as cargo, which costs significantly more. You must notify American when booking and provide health and vaccination records at check-in.

What is American Airlines' policy on carry-on bag size?

Carry-on bags must fit in the overhead bin or under the seat in front of you. American's size limit is 22 inches long by 14 inches wide by 9 inches deep. Bags larger than this may be checked at the gate at no charge if overhead space is full, though you may be asked to gate-check your bag.

How far in advance should I book an American Airlines flight?

Prices are generally lower when you book further in advance, though this varies by route and season. For domestic flights, booking two to three weeks ahead often yields better fares. For international flights, booking four to six weeks ahead is common. Prices can change daily, so setting up price alerts on the American website or using flight comparison tools can help you find lower fares.
