What if I get sick before my flight?


Editorial team Published on

If you get sick before a flight, you risk being denied boarding by the airline, worsening your symptoms from cabin pressure, or spreading illness to others.

Airline Policies and Denial of Boarding

  • Gate agents and crew: Staff have the right to deny boarding if you show clear signs of a contagious or severe illness (like persistent vomiting, high fever, or heavy coughing).
  • No-shows: Do not just skip the flight without telling the airline. Call before departure to avoid losing the value of your ticket entirely or being marked as a "no-show".
  • Medical waivers: Many airlines will waive change fees or extend ticket validity if you provide a doctor's note or medical certificate proving you were unfit to fly.

Health Risks of Flying Sick

  • Ear and sinus blockages: Cabin pressure changes during takeoff and landing can cause severe ear pain, ruptured eardrums, or blocked sinuses if you are congested.
  • Dehydration and fatigue: Recycled cabin air dries out your nasal passages and body, which can prolong your recovery time.
  • Contagious illness: Traveling with an active flu, COVID-19, or stomach virus puts other passengers and crew at risk.

What You Should Do

  • See a doctor: Get a dated medical certificate or a Fit-To-Fly statement immediately if you plan to request a refund or reschedule using medical provisions.
  • Contact your airline: Ask customer service about emergency rebooking or travel credit options.
  • Check insurance: Review your travel insurance policy if you purchased coverage; many plans cover trip cancellation due to sudden illness.
