Yes, in 2026, flight attendants have access to specific, curated passenger information through handheld digital devices (often called "In-flight Service Tablets"). This information typically includes your name, seat number, and frequent flyer status, which allows them to provide personalized greetings. They also see "service-related" data such as special meal requests (vegan, kosher, etc.), connection information for tight layovers, and any "special assistance" requirements like wheelchair needs or traveling with service animals. Crucially, for safety and security, they have access to a manifest that identifies "extraordinarily important" passengers or those with medical conditions flagged in the booking. However, in 2026, privacy laws like the GDPR and India’s DPDP Act strictly limit their access; they cannot see your credit card details, full home address, or private passport numbers. Their access is strictly "need-to-know" to ensure cabin safety and provide the level of service associated with your ticket class or loyalty tier.
