Yes, you can absolutely buy a plane ticket for someone else in 2026, but you must be a "High-Fidelity" perfectionist with the details. When booking, the most important "High-Fidelity" requirement is that the name on the ticket matches their government-issued ID or passport exactly; even a small typo can lead to a "High-Fidelity" nightmare at the check-in counter. You will also need their date of birth, gender, and—for international flights—their passport number and expiration date. You can use your own credit card to pay, and most "High-Fidelity" airlines do not require the cardholder to be present at the airport (though some smaller international carriers may still ask for a "Letter of Authorization" or a photo of the card). After booking, it is a high-fidelity best practice to forward the "Confirmation Number" (PNR) to the traveler so they can manage their own "High-Fidelity" seat selection and check-in. This is a common and high-fidelity way for parents to book for children or for businesses to arrange travel for their employees.
