    I’ve tried all that. How do I sue Frontier Airlines in small claims court?

    How much does it cost to file a complaint against Frontier Airlines in small claims?

    So how much are you going to spend filing a complaint against Frontier Airlines in small claims court?

    Court Filing Fees

    The amount you will pay to file a small claims lawsuit in California depends on how much you demand from Frontier Airlines. You will pay between $30 to $75 to file the lawsuit. 

    Note: If you cannot afford to pay court fees, you can ask the court to waive the fees.  

    Serving Costs

    Once the lawsuit is filed, you have to notify Frontier Airlines that you have sued them. This is called "serving." Serving Costs can range from $0-$75.

    More on who to serve on behalf of Frontier Airlines is below. If you win, you can request Frontier Airlines to pay for your court fees and serving costs.

    How much can you sue Frontier Airlines for in small claims?

    In California, you can sue Frontier Airlines for a maximum of $12,500 if you are an individual. If you are a business suing Frontier Airlines, you can sue for a maximum of $6,250. Note, if you are a sole proprietor, you count as an individual.

    By suing in small claims, you agree to waive any amount over the maximum amount you can sue for, even if you are owed more. For example, if Frontier Airlines owes you $13,000, and you decide to sue in small claims, you are waiving suing for an additional $500, which means that you will win a maximum of $12,500.

    While you may be missing out on the total amount you are owed, there are practical benefits to suing in small claims instead of suing in "regular court."

    Here are some of the benefits:

    1. Court filing fees are cheaper in small claims than in other courts.

    2. The process is faster in small claims than in other courts, as your hearing will usually be scheduled 30-70 days after you file the lawsuit.

    3. Lawyers are generally not allowed in small claims, which helps keep the costs of going to court low.  

    How to file a small claims lawsuit against Frontier Airlines

    Step 1: Complete "Plaintiff's Claim and Order to Go to Small Claims Court" (Form SC-100)

    When completing the small claims lawsuit, it is important to determine the correct legal entity name for Frontier Airlines. It seems that Frontier Airlines is owned by Republic Airways Inc. Make sure to review any contracts, receipts, or terms and conditions you have agreed to to confirm this information. 

    Step 2: File "Plaintiff's Claim and Order to Go to Small Claims Court"

    Each California Small Claims Court has a different procedure for filing. You have to check with your local small claims court whether they allow filing in-person, by mail, online, or fax. Or we can file your case for you!

    Step 3: Serve the lawsuit on Frontier Airlines’ agent

    Remember, you will be serving Frontier Airlines’  "agent for service of process" as listed on the California Secretary of State's website. Learn more here.

    What is a small claims court hearing like?

    Small claims hearings in California small claims are informal, and most hearings last around 15 minutes. While many disputes settle before the hearing, here is what to expect if your lawsuit does not settle.

    Who will represent Frontier Airlines at the hearing?

    • The easiest way to answer this question is that a lawyer will not represent Frontier Airlines since lawyers cannot represent parties at the initial small claims hearing. Instead, they will have a non-attorney representative.

    The hearing:

    • Right before the hearing, the judge will ask you and Frontier Airlines’ representative to show each other the evidence that you will later show the judge.

    • The judge will ask you why you filed a complaint.

    • The judge will ask Frontier Airlines’ representative to tell them their side of the story.

    • The hearing will only last around 15 minutes.

    • The judge will ask you to show them the evidence you brought. Sometimes the judge will keep the evidence. Other times, you will get the evidence right back.

    • Very rarely will a judge tell you whether you won or lost at the hearing. Instead, the judge will tell you that their decision will be mailed to you (usually takes a few weeks to two months or so).
