Where to log in to your Allegiant Air credit card account
The Allegiant Air credit card is issued by Barclays, so you log in through Barclays' online portal, not through Allegiant's website. Go to barclaycard.com and select "Log In" at the top of the page, then choose "Credit Card" from the menu. Enter your username and password — these are the credentials you set up when you first opened the card, not your Allegiant frequent flyer login.
If you have never logged in before, you will need to register first. On the Barclays login page, select "Enroll Now" and follow the prompts to create a username and password. You will need your card number and Social Security number to complete registration. This process takes about five minutes and gives you when ready access to your account.
Some cardholders also receive a separate login through Allegiant's rewards program portal, but that account only shows your points balance and redemption options — it does not let you pay your bill or view your statement. The Barclays portal is where you handle all account management.
Key Takeaways
- Log in at barclaycard.com, not through Allegiant Air's website, because Barclays issues the card.
- Your login credentials are separate from your Allegiant frequent flyer account and must be created during your first visit to the Barclays portal.
- You will need your card number and Social Security number to register for online access.
- The Barclays portal lets you view statements, make payments, and manage your account settings in one place.
What you can do once you are logged in
Once you access your account through Barclays, you can view your current balance, recent transactions, and available credit. You can also read or print statements going back several months, set up automatic payments, and change your mailing address or contact information. The portal shows your rewards points balance and lets you see how many points you have earned on recent purchases.
You can make a one-time payment or set up recurring monthly payments directly from the portal. If you want to pay by phone instead, Barclays' customer service number is on the back of your card. Payments made online typically post within one to two business days.
Resetting your password if you forget it
On the Barclays login page, select "Forgot Username or Password?" and enter your card number. Barclays will send a password reset link to the email address on file. Click the link and create a new password. The reset link expires after 24 hours, so complete the process the same day you request it.
If you do not receive the email, check your spam folder first. If it is not there, log out completely and try again, or call the customer service number on the back of your card and ask them to verify your email address on the account. They can also reset your password over the phone if you provide your Social Security number and card number.
Troubleshooting common login problems
If you see an error message saying your username or password is incorrect, make sure you are using the credentials you created during registration, not your Allegiant frequent flyer password. Passwords are case-sensitive, so check that Caps Lock is off. If you have tried multiple times and still cannot log in, wait 15 minutes before trying again — Barclays temporarily locks accounts after several failed attempts for security.
If the website itself is not loading, try a different web browser or clear your browser's cache and cookies. You can also try logging in from a different device to rule out a local connection problem. If the site is down for maintenance, Barclays usually posts a notice on barclaycard.com explaining the outage and when service will return.
Setting up two-factor authentication for added security
Barclays offers optional two-factor authentication, which sends a code to your phone or email each time you log in from a new device. To turn this on, log into your account, go to "Settings" or "Security," and select "Two-Factor Authentication." Choose whether you want codes sent by text or email, then verify your phone number or email address. Once activated, you will receive a code after entering your password on login.
Two-factor authentication makes it much harder for someone to access your account even if they have your password. You can turn it off at any time through the same settings menu, though Barclays recommends keeping it on for all financial accounts.
Mobile app login as an alternative
Barclays also offers a mobile app called "Barclaycard" that you can read from the Apple App Store or Google Play. You log in with the same username and password you use on the website. The app shows the same information — balance, transactions, points, and payment options — and some cardholders find it faster for checking their balance or making a quick payment.
The app uses your phone's security features (fingerprint or face recognition) once you log in the first time, so subsequent logins are faster. You can also set up push notifications to alert you when your statement is ready or when a large purchase is made on your card.
Frequently Asked Questions
Is the Barclays login the same for all Barclays credit cards?
Yes. If you have multiple Barclays cards, you log into all of them through the same barclaycard.com account using one username and password. Once logged in, you can switch between your different cards using a dropdown menu.
Can I log in to my Allegiant Air credit card account through the Allegiant website?
No. Allegiant's website does not host credit card account management. You must use barclaycard.com. Allegiant's website only lets you manage flight bookings and your frequent flyer account, which are separate from your credit card.
What should I do if I think someone else accessed my account?
Log in when ready and check your recent transactions. If you see charges you did not make, call the customer service number on the back of your card right away. Barclays can freeze your account, issue a new card, and dispute unauthorized charges. Report suspicious activity as soon as you notice it.
Do I need to create a separate login for the Allegiant rewards portal?
You may be able to link your Allegiant frequent flyer account to view your credit card points there, but this is optional. The Barclays portal is the main place to manage your account. Check your welcome materials or call customer service to learn whether Allegiant offers a linked rewards login.
