Canceling a flight due to injury generally entitles you to a refund only if you have a fully refundable ticket or travel insurance that covers "cancel for medical reasons." For standard non-refundable tickets, most airlines will not issue a cash refund, but they may provide a travel credit if you present a doctor's note certifying that you are "unfit to fly." In 2026, some regions (like India under updated DGCA rules) have introduced clearer mandates where airlines may offer a refund or credit if the passenger or a direct family member on the same PNR is hospitalized. Without these specific protections, you are at the mercy of the airline's "compassion policy," which is why experts strongly recommend third-party insurance for expensive international trips.
