For Ryanair and most other European carriers in 2026, you do not need to include your middle name on your flight booking. The airline's primary requirement is that your first and last name exactly match the details on your government-issued ID or passport. While it is considered "best practice" to include your full name as it appears on your passport to avoid any minor friction at the gate, skipping the middle name field is a standard and safe practice that will not result in denied boarding. However, a peer-to-peer "safety tip": if you have a hyphenated or double-barrelled first or last name, you must ensure you enter it exactly as it appears. Ryanair allows free "minor corrections" (up to 3 characters) within 48 hours of booking, but changing a name entirely after that window can trigger a fee of over £115. When in doubt, stick to your first and last name, but ensure the spelling is 100% accurate before clicking "purchase."
