A passenger approaches an automatic boarding kiosk, scans their passport, and the machine denies access. The name on the ticket does not match the MRZ area of the document. The flight departs in forty minutes. This scenario is becoming increasingly common since biometric e-gates have become widespread in European airports. Choosing the name on your plane ticket is not trivial, and the tolerance margins are shrinking.
MRZ Area of the Passport: The Absolute Reference for the Name on Your Plane Ticket
Most guides advise to “copy the name from the passport,” but the passport contains several text areas that are not always identical. In practice, what matters for automated systems is the MRZ (Machine Readable Zone), the two lines of characters printed at the bottom of the passport’s identity page.

This area does not always faithfully reproduce what is written at the top of the document. Accents disappear, hyphens are sometimes replaced by spaces, and the order of first names may differ from common usage. If you type “Jean-François” in the booking form while the MRZ shows “JEAN FRANCOIS” without a hyphen or accent, a biometric kiosk may block access.
The most reliable method: open your passport to the photo page, read the MRZ, and copy the name exactly as it appears, replacing any spaces with spaces. You can also find information on Voyage 2 Rêve that details this logic step by step.

Marital Name, Common Name, and Plane Ticket: What Airlines Really Accept
The case of the marital name remains the most frequent trap. On a French passport, the birth name always appears in the MRZ. The common name (spouse’s name) sometimes appears at the top of the document, but not systematically in the machine-readable area.
The PNR (Passenger Name Record) rules in force in the European Union push airlines to refuse any divergence between the reservation name and the identity document, even for a simple common name. Previously, on intra-Schengen flights, an agent at the counter would let it pass. With e-gates, this human filter disappears.
In practice, there are three situations:
- The passport only mentions the birth name in the MRZ: this is the name that must appear on the reservation.
- The passport mentions both the birth name and the spouse’s name (both appear in the MRZ): either can be used, but consistency must be maintained across all segments of the trip.
- The passport has been updated after marriage and the MRZ includes both names: choose the one you will also use for the ESTA, ETA, or future ETIAS if the destination requires it.
Alignment of Ticket, Passport, and Electronic Travel Authorization
This is an angle that few travelers anticipate. For destinations requiring electronic authorization (ESTA for the United States, ETA for Canada, ETIAS soon for third-country nationals entering the EU), authorities explicitly recommend aligning the ticket name with that of the authorization request.
A ticket booked in the common name and an ESTA filled out in the birth name may be considered inconsistent during checks, even if the passport mentions both. The system automatically cross-references databases. We are not talking about a benevolent human check, but an algorithm that compares strings of characters.
The operational rule: first fill out the electronic authorization, note the exact name used, then book the ticket with that same name, letter for letter. If you book the ticket before the authorization, keep the confirmation carefully to copy the name exactly in the ESTA or ETA form.
Special Characters, Compound First Names, and Input Errors on the Reservation
Online booking forms do not all accept the same characters. Some airlines refuse accents, while others automatically remove hyphens. Ryanair, for example, applies strict rules regarding name changes after booking, and correction fees can represent a significant portion of the ticket price.
For compound first names, the logic remains the same: follow the MRZ. If it shows “MARIE CLAIRE” as two separate words, enter two distinct first names (or a single field with a space, depending on the form). Never invent a format that the MRZ does not show.
If an error is detected immediately after purchase, some airlines offer a free correction window (often limited to a few hours). After this period, the modification procedure varies greatly from one airline to another. Feedback on this point varies: some customers obtain a minor correction free of charge by calling customer service, while others are charged the price of a new ticket.

Checks to Make Before Confirming Payment
- Compare each letter of the name entered with the MRZ of the passport (not with the top of the document, not with the identity card if traveling outside Schengen).
- Check that the first name matches the first name in the MRZ, not the common name or nickname.
- Ensure that the name used for the reservation is identical to that of the electronic travel authorization, if applicable.
- Re-read the booking confirmation received by email: some platforms truncate long names or remove characters without warning.
The increase in automatic blocks at e-gates makes these checks less optional than before. Every character counts: a missing letter or an extra hyphen is enough to trigger a denial at the kiosk, with no possibility of correction on site.
