How to Pay Your Southwest Airlines Credit Card Bill

Where and how to send your Southwest Airlines credit card payment

You can pay your Southwest Airlines Rapid Rewards credit card through three main routes: online through the card issuer's website, by phone, or by mail. The card is issued by Chase, so payments go to Chase, not to Southwest Airlines directly. Online payment is the fastest and most common method — you log into your Chase account, select the card, and authorize a payment to post within one to three business days. Phone payments go through Chase's automated system or a representative and typically post the same day if you call before the payment deadline.

Mail payments take seven to ten business days to reach Chase's processing center, so sending a check only makes sense if you have no internet access or phone service. The mailing address appears on your statement and in your online account. If you set up automatic payments through Chase's website, the full balance or a minimum payment you choose will deduct from your bank account on a date you select each month — this removes the risk of forgetting and triggering a late fee.

Key Takeaways

• Chase issues the Southwest Airlines Rapid Rewards credit card, so you pay Chase, not Southwest, and you can pay online, by phone, or by mail.
• Online and phone payments post within one to three business days; mail payments take seven to ten days, so plan ahead if you use the mail.
• Setting up automatic payments through your Chase account removes the risk of a missed payment and the late fee that follows.
• Late payments trigger a fee and can raise your interest rate, even if you pay just one day after the due date shown on your statement.
• If you cannot pay the full balance, paying at least the minimum by the due date stops a late fee, though interest will accrue on the unpaid balance.

How to pay online through Chase

Log into your Chase account at chase.com or through the Chase mobile app. Find the Southwest Airlines card in your account, then select "Make a Payment" or a similar option — the exact wording varies by app version. Enter the amount you want to pay (the full balance, minimum payment, or a custom amount), choose the bank account the money will come from, and pick the date you want the payment to leave that account. Review the details and confirm.

Chase will show you a confirmation number and an expected posting date. The payment will deduct from your bank account on the date you chose and post to your credit card within one to three business days. If you need the payment to post by a specific date to avoid a late fee, submit it at least three business days before your due date. If you miss the deadline, call Chase immediately — a single late payment can trigger a fee and a higher interest rate on future purchases.

Automatic payments and how to set them up

Automatic payments remove the need to remember a due date each month. In your Chase account, look for "Autopay" or "Automatic Payments" in the settings or account management section. You will choose a date each month (for example, the 15th), an amount (full balance, minimum payment, or a fixed dollar amount), and the bank account to draw from. Chase will then deduct that amount automatically on your chosen date every month until you cancel.

Most people set automatic payments to the full balance so they never carry interest charges. If you set it to the minimum payment, you will still owe interest on the unpaid balance, but you will avoid late fees. You can change or cancel automatic payments anytime through your account settings, and Chase will send you a confirmation email when the payment processes each month. This is the safest way to stay on time, especially if your work schedule or memory makes manual payments risky.

What happens if you miss the due date

A payment is late if it does not post to your account by 11:59 p.m. on the due date shown on your statement. Chase will charge a late fee — the amount depends on your balance and your account history, but it typically ranges from $25 to $40 for the first late payment. More importantly, a late payment can trigger a penalty APR (annual percentage rate), which is a much higher interest rate that applies to new purchases and sometimes to your existing balance.

A single late payment stays on your credit report for seven years and can lower your credit score, making it harder to borrow money or get approved for other credit cards or loans. If you realize you will miss the due date, call Chase before it passes — sometimes a representative can delay the posting date by a day or two, or they may waive a first late fee if you have a good payment history. After the due date passes, the damage is done, but paying immediately stops additional fees from piling up.

Minimum payments and how much you owe

Your minimum payment is the smallest amount Chase will accept to keep your account in good standing and avoid a late fee. It is usually 1 to 3 percent of your total balance, plus any fees or interest charges. You can find your minimum payment on your statement, in your online account, or by calling Chase. Paying only the minimum means you will owe interest on the unpaid balance at your card's APR, which for the Southwest Airlines card varies based on your creditworthiness.

If you carry a $5,000 balance and pay only the minimum each month, you will pay hundreds of dollars in interest over time and take years to pay off the card. Paying the full balance each month means you owe no interest at all. If you cannot pay the full balance, paying more than the minimum reduces the interest you owe and gets you out of debt faster. Many people use the minimum payment as a safety net when money is tight, but it should not be a long-term strategy.

Payment methods and which is fastest

Online payment through Chase's website or app is the fastest and most reliable method. You control the exact posting date, you get a confirmation number immediately, and there is no risk of a check getting lost in the mail. Phone payments through Chase's automated system or a representative also post quickly — usually the same day if you call before the payment deadline, though the exact timing depends on when you call and how busy the system is.

Mail payments are the slowest option and should only be used if you have no internet access or phone service. Write a check, include your account number on the check, and mail it to the address on your statement. Allow seven to ten business days for the check to arrive and post. If you are mailing a payment close to the due date, it will almost certainly arrive late, triggering a late fee. Never rely on mail for time-sensitive payments.

What to do if you cannot pay in full

If you cannot pay the full balance by the due date, pay at least the minimum to avoid a late fee and a penalty APR. The minimum is listed on your statement and in your online account. Paying the minimum keeps your account current and protects your credit score from an immediate hit, though interest will accrue on the unpaid balance at your card's APR.

If you are struggling with credit card debt, contact Chase to ask about hardship programs or payment plans. Some card issuers offer temporary lower interest rates or extended payment terms for people facing financial difficulty. You can also reach out to a nonprofit credit counselor through the National Foundation for Credit Counseling (NFCC) — they offer free or low-cost guidance on managing debt and budgeting. Do not ignore the bill or stop paying; that will damage your credit and may lead to collection action.

Frequently Asked Questions

Can I pay my Southwest Airlines credit card with a different bank account than the one I used to open the card?

Yes. When you make a payment online or by phone, you can choose any bank account you have access to. Chase does not require you to pay from the same account you linked when you opened the card. Just make sure the account has enough money to cover the payment, or the transaction will fail.

What if my payment posts after the due date but I sent it on time?

If you sent a check or initiated a payment before the due date but it posts after, you may still be charged a late fee. Mail and some payment methods take several days to post. To avoid this, submit payments at least three to five business days before your due date, or use online or phone payment for same-day or next-day posting.

Do I earn Southwest Rapid Rewards points when I pay my credit card bill?

No. Credit card payments do not earn rewards points. You earn points only when you use the card to make purchases. Paying your bill is a separate transaction that does not trigger rewards.

Can I set up automatic payments to a different bank account each month?

Most credit card issuers, including Chase, require you to link one or two bank accounts for automatic payments. You cannot change the account every month through autopay. If you need to pay from different accounts, make manual payments instead of using automatic payments.

What happens if I overpay my credit card?

If you pay more than you owe, the extra amount becomes a credit balance on your account. You can use that credit toward future purchases, or you can request a refund from Chase. Most people leave small overpayments on the account to cover the next month's charges.
