Traveling can be stressful. Make sure you know everything you need before you leave.
Traveling can be stressful. Make sure you know everything you need before you leave.
For international travel, additional airport, transportation, embarkation, security, and passenger service taxes/surcharges are government imposed and may apply depending on destination. For return travel from some countries, fares do not include airport and/or departure taxes, which may be collected by the foreign government.
All passengers, including children and newborns, are required to have a passport to leave, enter, or re-enter the United States. Please be sure to bring all required documents for your outbound and return flights. Visit Travel Gov for more information about document requirements.
Passport cards are not a valid substitute for a passport when traveling internationally by air. They may not be accepted as identification to check in for an international flight. They can be accepted for check-in on a domestic flight as it is government-issued ID.
You'll need to present your passport providing proof of citizenship and identity when you check in for international flights- it's the law. It's your responsibility to know what additional documentation is required for entry into any foreign country to which you are flying. So, please do your homework!
For travel documentation entry requirements, including visa requirements for other countries, please contact that country's consulate for information.
Note: You must meet the United States exit requirements, as well as the foreign country's entry requirements. Entry requirements are based on country of citizenship.
Your travel documents and identification may be checked on multiple occasions, so we suggest that you keep your documentation with you throughout your travels. If your documentation isn't adequate or sufficient, we simply can't allow you to board our aircraft. We want you to enjoy your trip, and we want you to come home as well!
If you're a citizen of another country and are traveling to the United States, we recommend that you contact the nearest United States Embassy or Consulate for the most current travel document requirements.
If you want to be ahead of the game, use online check-in or check-in on our mobile app before you even get to the airport! Online check-in for all our flights is available within 45 minutes to 24 hours of your departure time.
You and your baggage must be checked in for international flights at least one hour prior to departure. We strongly recommend coming to the airport 2-3 hours earlier during the busiest travel times, especially around the holidays. Please be prepared for significant TSA delays. In efforts to assist you certain ticket counters will open early, for more information view Travel Advisory page.
For the most part, Frontier's international rules for checked and carry-on baggage are the same for domestic travel as far as baggage allowance, size, and weight restrictions. However, baggage checked to or from Canada is subject to a maximum 70lbs weight limit. Read more about baggage requirements on our our baggage page.
If you have connecting Frontier flights on your arrival to the United States, you'll first need to go through Customs, collect your baggage, and then re-check your baggage to the final destination. Most customs areas have a connection check-in area available when you are through with your inspection, so it's easier than it sounds!
Frontier's baggage policies apply for travel on Frontier only. If you are connecting to or from another airline's international flight, the other airline’s baggage charges and allowances may apply in accordance with DOT regulations. Check the other airline's website for its baggage policies. What this means to you:

Traveling with minors to Canada
All minors must present their own, valid passports for international travel. For more detailed information on minors traveling to Canada please visit here. Passengers between the ages of 15 and 18 traveling to or from Canada are considered minors by Canadian standards.
If the minor is traveling with a person other than their parents or legal guardian:
The adult who is not the parent or legal guardian of the child must have written permission from the parents or guardians to travel with the child. The permission letter should include addresses and telephone numbers where the parents or legal guardian can be reached. A photocopy of the parents’ or legal guardian’s signed passports or national identity cards must be attached to the letter. The letter can be in the form of a single letter with signatures from both parents or a separate letter from each parent/guardian.
Minors between ages 15 and 18 yrs. of age

Depending on your citizenship, travel visas may be required to enter and leave some countries. If a visa is required, you can obtain it from the appropriate foreign consular representative before you proceed abroad. Allow sufficient time for processing the visa application, especially if applying by mail. Learn more about travel visas at Travel Gov.
International visitors to the U.S. from Visa Waiver Program countries may now apply for travel authorization online using the Electronic System for Travel Authorization. The tool is easy to use, free of charge, and available in many languages.
We recommend that you check with your healthcare provider or review your records to ensure your immunization (i.e. tetanus and polio) are up-to-date before travelling internationally. For detailed information about immunizations for foreign travel, please visit Travel Gov.
Some countries require proof of return or onward travel. For instance, Costa Rica will require you to show proof that you will be leaving their country unless you are a Costa Rican citizen. Proof of return or onward travel includes a return air ticket, a bus ticket, a cruise line ticket - something that shows you intend to leave the country. Be ready to show your proof of return or onward travel to the customer service representative or you may need to purchase a ticket at the airport before you leave for Costa Rica.
Once you have your boarding pass and have checked your baggage, head toward the security checkpoint area. Remember that you'll be asked for your boarding pass and photo identification when entering the security checkpoint line. Tickets and ticket confirmations (such as airline itineraries or documents from your travel agent) are not accepted at these checkpoints. Although we know your entire entourage wants to bid you farewell at the gate, unticketed customers won't be allowed beyond the security checkpoint.
If you are an FRONTIER Miles Elite level member, we invite you to look for the Priority Security Access Lane (where available) once you have checked-in and received your boarding pass.
Note: If you are meeting arriving passengers, you will want to allow enough time to obtain a gate pass and get through the security checkpoint to meet the flight.
When you're connecting to another flight within secure areas of an airport, you aren't required to check-in at the ticket counter again. You may check-in at the connecting gate for your flight.
The Transportation Security Administration (TSA) enforces the Secure Flight program to enhance the security of domestic and international commercial air travel through the use of an improved watch list to identify known and suspected terrorists.
Please review the TSA carry-on baggage policy.
The Department of Homeland Security (DHS) has implemented Secure Flight, a program developed to provide a uniform watch list matching by the Transportation Security Administration (TSA). By establishing one consistent watch list matching system, Secure Flight will enhance aviation security and help make travel easier for passengers.
We will send the information you provide to TSA, who will match it against terrorist watch lists. Note: that boarding passes may not always display the exact information you provided when booking your travel. This will not affect you when traveling. The name you provide when booking your travel is used to perform watch list matching before a boarding pass is ever issued.
Secure Flight makes travel safer by more effectively identifying individuals who may pose a known or suspected threat to aviation. It also enables officials to address security threats sooner. Furthermore, by creating one watch list matching system, it helps prevent the misidentification on of passengers who have names similar to individuals on terrorist watch lists. Lastly, Secure Flight offers an improved redress process, so that those who are mistakenly matched to the watch lists can avoid problems in the future.
The privacy of individuals' information is a cornerstone of Secure Flight. TSA collects the minimum amount of personal information necessary to conduct effective watch list matching. Furthermore, personal data is collected, used, distributed, stored, and disposed of in accordance with stringent guidelines and all applicable privacy laws and regulations
To learn more about Secure Flight, visit www.tsa.gov.
Those who believe they have been mistakenly matched to a name on the watch list are invited to apply for redress through the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP). Secure Flight uses the results of the redress process in its watch list matching process, thus preventing future misidentifications for passengers who may have a name that's similar to an individual on the watch list.
For more information on the redress process, visit www.dhs.gov/trip.
The Transportation Security Administration (TSA) requires you to provide your full name, date of birth, and gender for the purpose of watch list screening, under the authority of 49 U.S.C. section 114, the Intelligence Reform and Terrorism Prevention Act of 2004 and 49 C.F.R parts 1540 and 1560. You may also provide your Redress Number, if available. Failure to provide your full name, date of birth, and gender may result in denial of transport or denial of authority to enter the boarding area. TSA may share information you provide with law enforcement or intelligence agencies or others under its published system of records notice.
