Frontier Airlines' main customer service number is 1-801-401-9000

That number connects you to Frontier's general customer service line, where you can reach a representative for booking questions, changes to existing reservations, baggage issues, or general account help. Wait times vary by time of day and season, but calling early in the morning on a weekday typically means shorter holds than calling in the evening or on weekends.

Frontier also operates a separate line for passengers with disabilities or accessibility needs: 1-801-401-9000, extension 1. If you need to report a lost or damaged bag, you can also reach baggage services through the main number and ask to be transferred.

Key Takeaways

  • Frontier's main customer service phone number is 1-801-401-9000, available seven days a week.
  • You will need your confirmation number or ticket number ready when you call, which speeds up the process.
  • If you are calling about a flight that leaves within 24 hours, have your flight details visible so you can answer questions quickly.
  • Frontier does not charge a fee to speak with a representative by phone, but standard phone rates from your carrier explore.

What information to have ready before you call

Frontier's system will ask for your confirmation number first — this is the six-character code you received in your booking confirmation email. If you do not have that, you can provide your last name and the phone number or email address used to book the flight. Having this ready cuts your wait time in half.

If you are calling about a specific flight, have the flight number and date visible. For baggage claims or refund requests, have any receipts or documentation of the issue ready to reference. Representatives can often resolve problems faster when you can describe exactly what happened and when.

When to call versus using other contact methods

Phone is the fastest option if you need an when ready answer or have a complex issue — a flight change that involves multiple legs, a baggage problem that needs investigation, or a refund dispute. For straightforward questions like checking baggage fees or looking up a flight time, Frontier's website or mobile app will give you an answer in seconds without a wait.

Frontier also offers chat support through its website and app, which can work well if you are not in a hurry and prefer written communication. Email support exists but typically takes 24 to 48 hours for a response. If your flight leaves within 24 hours and you have a problem, phone is your best choice.

What to expect during the call

After you provide your confirmation number, the system will ask what you are calling about and may route you to a specific department — reservations, baggage, refunds, or general customer service. You may hear a wait time estimate, though the actual wait is often shorter or longer depending on call volume.

Representatives can book new flights, change existing reservations, process refunds for cancelled flights, file baggage claims, and answer questions about Frontier's policies on carry-ons, checked bags, and seat selection. They cannot override prices or offer discounts beyond what is already available on the website, but they can sometimes find alternative flights or routing options that the website does not show.

International calls and time zones

Frontier's customer service operates from 5 a.m. to 10 p.m. Mountain Time, seven days a week. If you are calling from outside the United States, the number is still 1-801-401-9000, but you will pay international long-distance rates through your phone carrier. Some international carriers charge significantly more for calls to the U.S., so check with your provider first if cost is a concern.

The 801 area code is based in Utah, which is in the Mountain Time Zone. If you are calling from the East Coast, that is two hours ahead; from the West Coast, one hour behind. Calling between 7 a.m. and 9 a.m. Mountain Time tends to have the shortest waits.

What Frontier cannot do over the phone

Frontier representatives cannot issue refunds for basic economy fares that were non-refundable at purchase — those are final sales. They also cannot waive baggage fees retroactively if you did not pay them at booking or check-in, though they can explain why a fee was charged and discuss options for future flights.

If you are disputing a charge on your credit card or have a complaint about how you were treated, the phone representative can document your concern and escalate it, but the actual resolution may take several business days and could involve a supervisor or the airline's customer relations department contacting you separately.

Frequently Asked Questions

Do I have to pay to call Frontier customer service?

Frontier does not charge a fee to speak with a representative, but your phone carrier's standard rates explore. Calling from a mobile phone may cost more than calling from a landline, depending on your plan. International calls are charged at your carrier's international rate.

What if I am calling about a flight that already departed?

If you missed your flight or need to rebook after a missed connection, call as soon as possible. Frontier can rebook you on the next available flight at no additional charge if the miss was due to a Frontier delay or operational issue. If you missed the flight for personal reasons, rebooking fees may explore.

Can I change my flight over the phone?

Yes. You can change your flight, passenger name, or seat assignment by phone. Some changes are free (like moving to a different flight on the same day), while others may have a change fee depending on your fare type and how far in advance you are making the change.

How long will I wait on hold?

Wait times range from a few minutes to over an hour depending on the time of day, day of the week, and current travel volume. Early mornings on weekdays are typically fastest. During peak travel seasons or after a major weather event, all lines may be busy.

What if I cannot reach anyone?

If the line is full, you can try again in 15 minutes, use the chat feature on Frontier's website, or send an email through the contact form. For urgent issues with a flight leaving within hours, chat support often has shorter waits than phone lines.
