Can You Fly With A Fever In 2023?

Do you have a fever and an upcoming flight? You may be wondering if it’s safe or even allowed to fly while running a temperature. With air travel rules frequently changing, especially post-pandemic, it’s a valid question.

If you’re short on time, here’s the quick answer: Flying with a fever is generally not recommended. Most airlines will likely prevent you from boarding if you have a severe fever over 100°F/38°C.

In this comprehensive guide, we’ll cover everything you need to know about flying with a fever in 2023. We’ll look at airline policies, medical advice, what to do if you get a fever before your flight, and tips for staying healthy while traveling.

Airline Policies on Flying with a Fever

As we enter 2023, air travel continues to adapt to the ongoing pandemic. One of the primary concerns for airlines is ensuring the safety and well-being of passengers and crew members. In light of this, many airlines have implemented specific policies regarding flying with a fever.

Temperature Screenings at Airports

Temperature screenings have become a common sight at airports around the world. Passengers are required to undergo a quick and non-invasive temperature check before boarding their flights. This measure is aimed at identifying individuals with a fever, which is one of the symptoms commonly associated with COVID-19.

Airlines have collaborated with airport authorities and health organizations to ensure that these screenings are conducted efficiently and effectively.

It is important to note that a fever alone does not necessarily mean an individual has COVID-19. However, it is an indication that further assessment may be required. If a passenger is found to have an elevated temperature, they may be subject to additional screening or denied boarding, depending on the airline’s policies.

Denied Boarding for Fevers

Several airlines have implemented policies that restrict passengers with a fever from boarding their flights. This measure is in place to prevent the potential spread of infectious diseases, including COVID-19.

Passengers who are visibly unwell or have a high temperature may be denied boarding, even if they have a valid ticket.

The specific guidelines and thresholds for fever may vary between airlines. Some airlines may require a temperature below a certain threshold, while others may take other factors into consideration, such as the individual’s overall health condition.

It is crucial for passengers to familiarize themselves with the policies of the airline they are flying with to avoid any surprises or inconvenience at the airport.

International Travel Restrictions

International travel has been significantly impacted by the global pandemic. Many countries have imposed travel restrictions and entry requirements to limit the spread of COVID-19. These restrictions may include mandatory quarantine, COVID-19 testing, or proof of vaccination.

It is important for travelers to stay informed about the latest travel advisories and requirements for their intended destination.

Airlines are closely following these international travel restrictions and aligning their policies accordingly. Passengers with a fever may face additional scrutiny or be denied boarding if they are traveling to a country with strict entry requirements.

It is advisable to check the official government websites or the airline’s website for the most up-to-date information before traveling.

Medical Advice on Flying with a Fever

When it comes to flying with a fever, it is important to consider your own health and the safety of other passengers. While it may be tempting to push through and continue with your travel plans, there are some important factors to consider.

Dangers of Flying with a High Fever

Flying with a high fever can be risky for both the individual with the fever and those around them. Elevated body temperature can indicate an underlying infection or illness, which may compromise the immune system and increase the risk of spreading contagious diseases.

Air travel often involves being in close proximity to others for an extended period of time, which can facilitate the transmission of illnesses.

Furthermore, the changes in cabin pressure and altitude during a flight can worsen symptoms for individuals with a fever. The decrease in oxygen levels inside the aircraft can make breathing more difficult and increase discomfort.

According to the Centers for Disease Control and Prevention (CDC), individuals with a fever of 100.4°F (38°C) or higher should not travel by air. This guideline is in place to protect the health and well-being of both passengers and crew members.

Precautions to Take If You Must Fly While Sick

If you absolutely must travel by air while sick with a fever, there are some precautions you can take to minimize the risk of spreading illness:

  • Consult with a healthcare professional: Before making any decisions, it is important to seek medical advice. A healthcare professional can provide guidance on whether it is safe for you to fly and offer recommendations for managing your symptoms during the journey.
  • Notify the airline: Inform the airline about your condition before your flight. They may have specific protocols in place to accommodate passengers who are ill.
  • Wear a mask: Wearing a mask can help prevent the spread of respiratory droplets, which is one of the main ways illnesses are transmitted. It can also provide some protection for the individual wearing it.
  • Maintain good hand hygiene: Wash your hands frequently with soap and water or use hand sanitizer with at least 60% alcohol content. Avoid touching your face, especially your eyes, nose, and mouth.
  • Stay hydrated: Drink plenty of fluids to prevent dehydration, which can worsen symptoms.
  • Consider rescheduling: If your travel plans are not urgent, it may be best to postpone your trip until you have fully recovered.

Remember, the health and safety of yourself and others should always be the top priority. If you are unsure about whether it is safe to fly with a fever, it is best to consult with a healthcare professional for personalized advice.

What to Do if You Get a Fever Before Your Flight

Planning a trip can be exciting, but sometimes unexpected circumstances arise. One such circumstance is getting a fever right before your flight. While it’s always best to consult with a medical professional, here are a few steps you can consider taking if you find yourself in this situation.

Consider Postponing Your Trip

If you’re experiencing a fever, it may be wise to consider postponing your trip. Flying with a fever can not only be uncomfortable for you, but it can also put other passengers at risk. Additionally, some airlines may have specific policies in place regarding passengers with fevers, and it’s important to respect and adhere to these guidelines for the safety of everyone involved.

Get Tested for COVID-19

In the midst of the ongoing COVID-19 pandemic, it’s crucial to rule out the possibility of having contracted the virus. Getting tested for COVID-19 can help determine the cause of your fever and ensure that you’re not unknowingly exposing others to potential infection.

Contact your healthcare provider or visit a local testing center to get tested as soon as possible.

Alert the Airline and Get a Doctor’s Note

If you decide to proceed with your flight despite having a fever, it’s important to inform the airline about your condition. Airlines may have specific protocols in place for passengers with fevers, and they may require additional documentation or a doctor’s note.

This information will help the airline make necessary arrangements and ensure the safety of all passengers on board.

Remember, the health and well-being of yourself and others should always be a top priority. By taking the appropriate steps and following the guidelines of medical professionals and airlines, you can make an informed decision about whether or not to fly with a fever.

Tips for Staying Healthy While Traveling

Get Plenty of Rest Before Your Trip

One of the best ways to stay healthy while traveling is to ensure you get plenty of rest before your trip. Lack of sleep can weaken your immune system, making you more susceptible to illnesses. Aim for at least 7-8 hours of sleep each night leading up to your travel day.

This will help boost your immune system and give you the energy you need for your journey.

Stay Hydrated

Staying hydrated is crucial for maintaining good health while traveling. Dehydration can lead to fatigue, headaches, and even weakened immune function. Make sure to drink plenty of water throughout your journey, especially on long flights or road trips.

Avoid excessive consumption of alcohol or caffeinated beverages, as they can contribute to dehydration. If you’re traveling to a destination with limited access to clean drinking water, consider carrying a reusable water bottle with a built-in filter.

Wash Hands Frequently

Keeping your hands clean is one of the simplest and most effective ways to prevent the spread of germs. Wash your hands frequently with soap and water for at least 20 seconds, especially before eating, after using the restroom, and after touching high-touch surfaces such as doorknobs or handrails.

If soap and water are not available, use hand sanitizer with at least 60% alcohol content. Avoid touching your face, especially your eyes, nose, and mouth, as this can introduce germs into your body.

Travel with Medicine and First Aid Supplies

It’s always a good idea to travel with a small supply of medicine and first aid supplies. Include items such as pain relievers, fever reducers, cold and flu medication, adhesive bandages, and antiseptic wipes. These supplies can come in handy in case of minor injuries or common ailments.

Make sure to pack them in your carry-on luggage for easy access during your journey.

Remember, these tips are general guidelines for staying healthy while traveling. It’s always a good idea to consult with a healthcare professional before your trip, especially if you have any pre-existing medical conditions or concerns.

By taking proactive measures and being prepared, you can enjoy a safe and healthy journey.


We hope this guide gave you a comprehensive overview on whether or not you can fly with a fever in 2023. While each airline has specific policies, most will prevent you from boarding if you have a high fever over 100°F/38°C. If trying to fly while sick, take proper precautions.

Your health and the health of others should be your top priority. Safe travels!

The key points to remember are: get tested if you have flu-like symptoms, follow your doctor’s advice, be upfront with the airline, and take measures to avoid spreading illness. With some planning and extra care, you can still travel while managing a mild fever or illness.
