Editorial Review: This guide has been reviewed by the FlyTripInfo editorial team using publicly available Frontier Airlines policies to provide independent travel guidance. 

Quick answer: Frontier Airlines offers customer support through phone, live chat, and WhatsApp. Most booking changes, baggage purchases, and seat selection can also be managed through the Frontier app. Since Frontier is an ultra-low-cost airline, many services are self-managed and optional extras are charged separately.

Frontier Airlines Contact Options

Frontier Airlines offers three official customer support channels, available 24/7 for most travel-related questions. 

Channel	How to Reach It
Phone	Call 602-333-5925, +1-855-510-5187
Live chat	Start a chat on Frontier’s website
Text	Message Frontier on WhatsApp

For most routine bookings and travel questions, the Frontier mobile app is often faster than waiting on any of these three. One thing worth flagging early: Frontier currently requires check-in through its app rather than its website. If you’re used to checking in from a browser on other airlines, download the app well before your travel day so this doesn’t catch you off guard.

When Should You Contact Frontier vs. Use the App?

Contact Frontier directly for anything the app can’t fix — a cancelled flight, a lost bag, a refund, or a name correction on your ticket. For routine tasks, the app is usually faster, since it’s built specifically for Frontier’s check-in and booking process.

Contact Frontier if you need to:

• Rebook after a cancellation or major delay
• Report lost, delayed, or damaged baggage
• Request a refund
• Correct a name error on your ticket
• Arrange special assistance

You can usually handle these yourself in the app:

• Checking in — this can’t be done on the website
• Downloading your boarding pass
• Checking flight status
• Adding a bag or selecting a seat
• Managing your booking

What Can Frontier Customer Service Help With?

Frontier customer service can help with bookings, flight changes, refunds, baggage issues, special assistance, and other common travel questions. 

Issue	Best Way to Get Help
Flight cancellation / rebooking	Phone or live chat
Refund request	Live chat or online form
Lost or delayed baggage	Airport desk, then phone
Seat selection issue	App
Name correction	Phone or live chat
Special assistance	Phone, arranged in advance

A same-day cancellation needs a fast response, so phone tends to work better than chat during a widespread disruption, when a lot of other travelers are reaching out at once too.

What Should You Have Ready Before You Contact Support?

Keep your confirmation number, the name on your ticket, and your flight number and date on hand. This alone speeds up almost any call or chat.Having these details ready can help Frontier verify your booking and resolve your request more quickly. 

Before reaching out, gather:

• Confirmation number
• Name exactly as it appears on your ticket
• Flight number and travel date
• Baggage tag number, if it’s a baggage issue
• Photos of any damage
• A clear idea of what you want — refund, rebooking, or credit

Saying your preferred outcome upfront — “I need to be rebooked” instead of just describing what happened — tends to move things along faster.

Flight Changes, Cancellations, and Refunds

Frontier lets you change or cancel most bookings through the app or by phone, though fees depend heavily on your fare, since Frontier’s cheapest fares are the most restrictive by design.

If Frontier cancels or significantly delays your flight, you’re generally entitled to rebooking or a refund. If you’re the one cancelling, what you get back depends on your fare rules — worth checking before you call, since it tells you upfront what’s actually possible. If you’re still deciding on seating for an upcoming trip, our Frontier Seat Selection Guide explains how seat fees work and what to expect if you’ve already paid for a preferred seat. 

Baggage Support

Frontier customer support can help with delayed, lost, or damaged baggage. If you experience a baggage problem, report it as soon as possible so your request can be processed quickly. 

1. Delayed baggage — report it at the Frontier baggage desk before leaving the airport and get a reference number
2. Lost baggage — if it isn’t found within Frontier’s search window, you’ll likely need to file a formal claim
3. Damaged baggage — report it as soon as you notice it, ideally before leaving the airport

Frontier charges separately for carry-on and checked baggage on most fares. Before you travel, check our Frontier Airlines Baggage Fees guide to understand baggage charges, and our Frontier Carry-On Rules guide to see what you can bring onboard.

If you’re comparing baggage policies across airlines, explore our Airline Baggage Fees Hub. You can also compare cabin baggage limits in our Carry-On Rules Hub. 

Seat Selection and Special Assistance

Frontier customer service can also provide travel assistance for passengers who need additional support before or during their journey. 

Seat selection on Frontier is almost always a paid add-on rather than something bundled into your fare. If it isn’t working correctly in the app, contacting support directly is reasonable — but for simply picking a seat, the app itself is usually the faster route.

For special assistance, Frontier can arrange wheelchair help, medical support, and assistance for unaccompanied minors. Request this by phone as early as possible, ideally well before your travel date, since same-day arrangements are harder to guarantee.

Why Frontier Customer Service Is Different

Frontier is an ultra-low-cost carrier, and that shapes both its pricing and its support model. Nearly every extra — bags, seats, and sometimes even a printed boarding pass at the airport — is priced separately, and check-in is app-only rather than website-based.

A few practical things this means for you:

• Don’t expect bundled extras the way you might on a full-service airline — check what your specific fare includes before assuming something is a support issue versus a paid add-on you skipped at booking
• Frontier encourages travelers to manage many parts of their trip through its mobile app, including check-in, boarding passes, and booking changes. 
• Expect a leaner support setup overall — three official channels rather than a long list of options, which is part of how Frontier keeps costs low

This isn’t a criticism of the airline, just a structural difference worth knowing going in, since it changes what you should expect compared to a legacy carrier.

What If You Can’t Reach Frontier?

If phone or chat lines are busy, try Frontier’s other official channels, since some issues — like seat changes — can be resolved directly in the app without needing to speak to anyone.

• Try WhatsApp if phone hold times are long
• Use live chat if you’d rather not call
• Check the app first for anything that might be self-service
• If your issue isn’t urgent, trying another contact method may help reduce wait times. 
• For unresolved disputes, the U.S. Department of Transportation accepts airline complaints after you’ve gone through Frontier’s own process

Common Situations Travelers Face

Your flight is cancelled

Phone is usually your best bet for immediate rebooking, especially during weather disruptions when everyone’s contacting support at once.

Your bag doesn’t arrive

Report it at the airport baggage desk before leaving and get a reference number to track it.

You want a refund instead of a rebooking.
Live chat or the online form typically handles this, though it takes a few days to process either way.

You notice a misspelled name after booking.
Contact Frontier by phone or chat as soon as you can — corrections are easier before check-in opens.

You forgot the app is required for check-in.
Download the Frontier app as early as possible before your flight, since check-in isn’t available through the website.

Before You Travel

Before your flight, review your booking, complete check-in through the Frontier app, and confirm any baggage or seat purchases. Since airline policies can change, always verify the latest information before departure.
