Frontier Airlines' main customer service number is 1-800-432-1359

That number connects you to Frontier's general customer service line, where representatives handle booking questions, flight changes, baggage issues, and most other concerns. The line is open seven days a week, though wait times vary by time of day and season. You will hear an automated menu that routes you to the right department based on what you need.

Frontier also operates a separate number for reservations: 1-800-432-1359 (the same line handles both). If you are calling about a specific reservation, have your confirmation number ready — it speeds up the process. The airline does not charge extra for phone support, though your regular phone plan's long-distance rates explore if you are calling from outside the continental United States.

Key Takeaways

  • Frontier's main customer service number is 1-800-432-1359, open every day of the week.
  • Have your confirmation number handy when you call about a reservation, as it helps the representative locate your booking faster.
  • Wait times are typically shorter on weekday mornings and longer during evening hours and weekends.
  • Frontier also offers support through its website chat feature and social media accounts if phone lines are busy.
  • International callers should check Frontier's website for region-specific numbers, as rates and routing differ by country.

What to expect when you call

When you dial 1-800-432-1359, you will hear an automated voice menu. The system asks what you need — booking a flight, changing a reservation, reporting baggage damage, or something else. Select the option that matches your reason for calling. This routes you to the correct department and usually reduces your wait time compared to selecting a generic option.

After you select your reason, you will wait in a queue. During peak travel times (early morning, evening, holidays, and weekends), waits can stretch to 30 minutes or longer. During slower periods, you might reach someone in five to ten minutes. The system will tell you your approximate wait time and offer to call you back instead of holding — if you choose this option, Frontier calls your number when a representative is ready.

Have the following information ready before you call: your confirmation number, the names of all passengers on your reservation, your phone number, and your email address. If you are calling about baggage, have your baggage tag number. If you are reporting a problem with a flight, have the flight number and date. This information helps the representative work through your issue faster.

When phone support is not your fastest option

Frontier's website offers a chat feature that sometimes has shorter waits than the phone line. You can access it at frontier.com by clicking the chat icon, usually found in the lower right corner of the page. Chat works during the same hours as phone support and handles many of the same issues — booking changes, baggage questions, and general inquiries.

For straightforward changes like seat selection or adding a checked bag to an existing reservation, the Frontier website and mobile app let you make the change yourself without calling. Log in with your confirmation number and email address, and you can modify most bookings in minutes. This avoids the phone queue entirely if your issue is straightforward.

Frontier also responds to messages on Facebook and Twitter, though response times are slower than phone or chat — usually several hours. Use social media if you have already tried phone and chat without reaching someone, or if you prefer written communication.

International phone numbers and calling from abroad

If you are calling from outside the United States, Frontier's main number may not work or may route you to an international operator with higher charges. The airline maintains a list of country-specific numbers on its website under "Contact Us." These numbers connect you to the same customer service team but route through local carriers, which can reduce your phone bill.

Common international numbers include +1-720-374-4747 for calls from Canada and +44-203-769-8723 for calls from the United Kingdom, though these numbers and their availability change. Before calling from abroad, visit frontier.com and search for your country to confirm the current number. Some countries do not have a direct Frontier line, in which case the website will direct you to a partner service center.

What you cannot do by phone

Frontier does not process refunds over the phone for most situations. If you are owed a refund — for a cancelled flight, for example — the airline issues it to your original payment method within 7 to 10 business days. You can check the status of a refund on the website by entering your confirmation number, but the phone representative cannot speed up the process or change the timeline.

You also cannot purchase a ticket by phone with Frontier. The airline requires all bookings to be made through the website, mobile app, or through a travel agent. If you need help using the website to book, phone representatives can walk you through the steps, but they cannot complete the purchase for you.

Troubleshooting common phone issues

If you reach a busy signal or the call drops, try calling back after 15 minutes. Frontier's phone system does not use a traditional busy signal — if you cannot connect, it usually means all lines are full. Waiting and trying again is more reliable than staying on hold.

If the automated menu does not recognize your issue, select "Other" or "Customer Service" to reach a representative who can route you correctly. Do not hang up and call back, as you will start over in the queue. The representative can transfer you to the right department faster than the automated system can.

If you are calling about a flight that departs within 24 hours, mention this when the automated system asks your reason. Frontier prioritizes calls about imminent flights, and you may reach someone faster by selecting this option even if your issue is not strictly urgent.

Frequently Asked Questions

Is there a fee to call Frontier customer service?

Frontier does not charge a separate fee for phone support. You pay only what your phone plan charges for the call. If you are calling from a mobile phone, standard long-distance or mobile rates explore depending on your plan. Calling from a landline within the continental United States is typically a local or toll-free call.

Can I reach Frontier by phone if my flight is cancelled?

Yes, and cancelled flights are prioritized in the phone queue. Call 1-800-432-1359 and tell the automated system your flight was cancelled. You will usually reach someone faster than for routine questions. The representative can rebook you on the next available Frontier flight or discuss other options.

What time of day has the shortest wait?

Weekday mornings between 8 a.m. and 11 a.m. Eastern Time typically have shorter waits than evenings or weekends. Avoid calling during the hour before a flight departs, as many passengers call with last-minute questions. Late night calls (after 10 p.m.) sometimes have shorter waits because fewer people are calling.

Can I reach a real person when ready, or do I have to go through the automated menu?

You must go through the automated menu first. Frontier does not offer an option to skip it and reach a representative directly. However, selecting the option that best matches your reason for calling usually gets you to a person faster than selecting a generic choice.

What should I do if I cannot understand the automated menu?

Say "representative" or "agent" at any point during the automated menu, and the system will transfer you to a person. You will wait in the general queue, but you will not have to navigate the menu. This works if you are calling from a phone that recognizes voice commands.
