Serving more than 120 destinations throughout North and Central America, Frontier is a low-cost airline ideal for budget-conscious travelers. Unfortunately, discount airlines aren’t always known for the highest level of service and perks are few and far between. When your experience with Frontier is subpar, whether that’s for excessive flight delays, a canceled flight, poor service, or anything else, complaints make sense.

Frontier Airlines doesn’t have the best complaints track record. According to the OACP (US Office of Aviation Consumer Protection). In 2023, Frontier was the worst airline overall with a complaints average of 32.99 for every 100,000 customers. The next closest was Spirit Airlines, but they had fewer than 15 complaints for every 100,000 passengers.

Frontier Airlines Contact Info

When you need Frontier contact information to reach out for a complaint, you can use the website’s online forms, live chat, text via WhatsApp, the Frontier app, or call. It’s also possible to use social media if you need to draw attention to your Frontier complaint.

Frontier Airlines Customer Service

When you have an urgent complaint, like re-booking due to a Frontier flight cancellation or delay, sometimes calling is the best way to get a quick answer. Otherwise, the airline prefers that you use their online forms or chat options as the customer service contact options.

Frontier Phone Numbers

Frontier Airlines has a toll-free phone number that operates 24 hours, but there are limits on which passengers are permitted to call. Your situation needs to fit into one of the following:

• You have upcoming travel within 24 hours
• You recently completed travel within 24 hours
• You are an Elite member

Tips For Calling Frontier Airlines

• Preparation is key: When you call Frontier Airlines, have all your relevant documents and information ready, such as your booking details, flight number, and any correspondence. This helps you avoid the hassle of needing to call back.
• Avoid busy times: Airline support centers are often busiest during lunchtime, on weekends, or after significant disruptions like widespread weather events or strikes.
• Make a few notes: It can be tough to remember everything that was discussed on a call. After your conversation, jot down a quick summary of key points to help you recall details later, should you need to reference the call. Also, note down your call’s reference number.
• Be polite but assertive: Customer service agents are more likely to help if you maintain a calm and respectful tone. However, be clear and firm about your issue and what resolution you are seeking. If necessary, ask to speak with a supervisor if you feel your issue is not being handled properly.
• Use Frontier’s online tools first: As mentioned, calls are reserved for those within 24 hours of travel, and Frontier Airlines offers a variety of online tools for managing bookings, checking flight status, and resolving common issues. Try using their website or mobile app to handle your request before calling, as this could save you time.
• Follow up if needed: If you don’t get a resolution within the timeframe you were promised, don’t hesitate to call back and reference your case number. Persistent, polite follow-up can often lead to quicker resolutions.

Frontier Airlines Online Contact Info

Website Forms

Within the Customer Service section of the website, you’ll find a selection of online form options. These range from “File a complaint” to “Delays and Cancelations” and “Refund Request.” When you initiate Frontier Airlines complaints via the forms, you’ll have a record of the submission from a generated ticket or reference number, which will help with follow-up. 

Frontier Airlines Email

There is no published Frontier Airlines contact email address, but you can start a conversation using WhatsApp or any of the online forms appropriate to your situation on the Customer Service page.

Frontier Airlines Live Chat

Like the phone lines, the live chat feature is available 24-7 and is accessible from the Customer Service section. 

Frontier Airlines Social Media

When the normal channels aren’t giving your complaint the attention it deserves, consider adding social media to your Frontier Airlines contact options. @FlyFrontier is their handle for X and Instagram, and you can simply search for the company name on Facebook.

Advice if Frontier Airlines Doesn’t Reply

When you haven’t received a significant response (other than a confirmation of receipt) within 60 days, it’s definitely time to take action. This can be anything from using social media to escalation to using AirAdvisor for assistance. We can help with certain complaints related to flight delays and cancelations, denied boarding, and missed connections.

Tips For a Successful Frontier Airlines Complaint

• File it quickly: Starting your complaint as soon as possible is ideal. It means you won’t miss any Frontier-imposed deadlines and all the complaint information will remain fresh in your mind.
• Make sure your contact info works: It’s likely that Frontier will have questions or need to follow up with you. Ensure they have a regularly-checked email and a correct phone number.
• State expectations: Be clear about what it will take to resolve your issue. This should help Frontier address it quickly.
• Attach all necessary documents: Make sure you also send in all the supporting documentation you have. This includes receipts, photos, boarding passes, luggage tags, etc.
• Don’t let it go: If your complaint is ignored, be persistent. This means consistently following up, escalating, and taking to social media.

Frontier Airlines Compensation Forms

Frontier has a specific online form that deals with delays of more than 3 hours and flight cancelation. There is also a section for refund requests and a delayed or damaged bag. Although there is no official requirement for US-based airlines to issue compensation for flight interruptions, most airlines will re-book you on the next available flight for a cancelation. Additionally, they should keep you comfortable during long delays by providing refreshments and hotel stays for overnight delays.

If your Frontier Airlines complaint is more general or related to bad service, you should choose the option that simply states “File a complaint.”

How Do You File Your Frontier Complaint?

Always opt for complaints in writing when possible. This includes WhatsApp and live chat, but ideally, you should use the related online form. Some require you to log in, whereas others just ask for all your details.

When you’re submitting the free-form section of any complaint, these templates can help you get started and keep you on track:

• Poor service template
• Refund request template
• Flight interruption template

If you prefer to use our expertise instead, we can always file your complaint for flight problems for you. With a 98% success rate and a no-win, no-fee structure, trust our airline compensation experts to get results.

How to Proceed When the Frontier Airlines Forms Don’t Work

This is a situation where you will need to contact the airline via live chat or WhatsApp. You can also call if it’s within 24 hours of your flight. Social media is another way to expose the issue of non-functioning forms that may get attention as others comment.
