What Southwest Bill Pay offers and how to use it

Southwest Airlines does not operate a traditional bill pay system because most customers pay for flights at the time of booking rather than receiving an invoice later. However, if you have a Southwest credit card, a gift card balance to manage, or an outstanding balance on your account, you can pay through Southwest's website or by phone. The fastest route is logging into your Southwest account at southwest.com, selecting "Manage Reservations," and using the payment option there. If you prefer not to use the website, you can call Southwest's customer service at 1-800-I-FLY-SWA (1-800-435-9792) and provide payment information over the phone.

If you hold a Southwest Rapid Rewards credit card, your bill comes from the card issuer (Chase Bank), not from Southwest itself. You would pay that bill through your Chase online account or by mailing a check to the address on your statement. This is separate from any balance you might owe Southwest directly for a flight or service.

Key Takeaways

  • Most Southwest payments happen at booking, but you can pay an existing account balance by logging into southwest.com or calling 1-800-I-FLY-SWA.
  • If you have a Southwest credit card, the bill comes from Chase Bank, not Southwest, and you pay it through your Chase account or by mailing a check.
  • Southwest does not accept third-party bill pay services like Venmo, PayPal, or bank bill pay systems for flight payments.
  • Payments made online through your Southwest account are processed immediately, while phone payments may take one business day to post.

Paying a Southwest account balance online

To pay a balance you owe Southwest directly, go to southwest.com and sign into your Rapid Rewards account. Click on "Manage Reservations" and look for any outstanding balance or credit card payment option. You can enter a debit card, credit card, or bank account information. Southwest accepts Visa, Mastercard, American Express, and Discover. The payment posts to your account immediately.

If you do not have an online account or prefer not to create one, call 1-800-I-FLY-SWA and speak with a representative. They can take payment over the phone using the same card types. There is no fee for paying by phone, but the payment may take up to one business day to appear in your account.

Paying your Southwest credit card bill

The Southwest Rapid Rewards credit card is issued by Chase Bank, so your monthly bill and payment instructions come from Chase, not from Southwest. You can pay online through your Chase account at chase.com, by phone at the number on your statement, by mail, or through your bank's bill pay system.

Mail payments to the address printed on your statement. Include your account number and the payment amount. Allow 5 to 7 business days for a mailed check to reach Chase and post to your account. If you are close to your due date, paying online or by phone is faster and safer.

Payment methods Southwest does and does not accept

Southwest accepts credit cards (Visa, Mastercard, American Express, Discover), debit cards, and bank account transfers when you pay through southwest.com or by phone. The company does not accept PayPal, Venmo, Apple Pay, Google Pay, or other digital wallets for flight or account payments.

You cannot set up automatic recurring payments through Southwest's website for future flights. If you want to automate payments, you would need to use your bank's bill pay system to send a check to Southwest's mailing address, though this is slower and less common. Most customers simply pay at the time they book a flight.

Mailing a check to Southwest

If you prefer to pay by mail, send a check to Southwest Airlines, P.O. Box 37001, Dallas, TX 75235. Write your Rapid Rewards number or confirmation number on the check. Mail takes 5 to 10 business days to arrive, and Southwest may take another 2 to 3 business days to process and post the payment. If you have an urgent balance or a flight coming up soon, paying online or by phone is much faster.

Include a note with your check if the payment is for a specific reservation or account issue. This helps Southwest's payment processing team apply the money to the correct account.

What happens if you miss a Southwest payment

If you have a balance on your Southwest account and do not pay it, Southwest may prevent you from booking new flights until the balance is settled. If the balance is on a Southwest credit card issued by Chase, missing a payment will be reported to credit bureaus and can lower your credit score. Chase will also charge late fees and may increase your interest rate.

If you are unable to pay a balance, contact Southwest or Chase as soon as possible. Some customers have been able to work out payment plans, though this is not may provide. The sooner you reach out, the more options you may have.
